For example, this template uses a long volume name:</p> <dl> <dd> <code>{{cite book |title=Title |date=May–Jun 2021 |volume = 1: Long volume}}</code> <dl> <dd> <style data-mw-deduplicate="TemplateStyles:r1238218222">.mw-parser-output cite.citation{font-style:inherit;word-wrap:break-word}.mw-parser-output .citation q{quotes:"\"""\"""'""'"}.mw-parser-output .citation:target{background-color:rgba(0,127,255,0.133)}.mw-parser-output .id-lock-free.id-lock-free a{background:url("//upload.wikimedia.org/wikipedia/commons/6/65/Lock-green.svg")right 0.1em center/9px no-repeat}.mw-parser-output .id-lock-limited.id-lock-limited a,.mw-parser-output .id-lock-registration.id-lock-registration a{background:url("//upload.wikimedia.org/wikipedia/commons/d/d6/Lock-gray-alt-2.svg")right 0.1em center/9px no-repeat}.mw-parser-output .id-lock-subscription.id-lock-subscription a{background:url("//upload.wikimedia.org/wikipedia/commons/a/aa/Lock-red-alt-2.svg")right 0.1em center/9px no-repeat}.mw-parser-output .cs1-ws-icon a{background:url("//upload.wikimedia.org/wikipedia/commons/4/4c/Wikisource-logo.svg")right 0.1em center/12px no-repeat}body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-free a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-limited a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-registration a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-subscription a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .cs1-ws-icon a{background-size:contain;padding:0 1em 0 0}.mw-parser-output .cs1-code{color:inherit;background:inherit;border:none;padding:inherit}.mw-parser-output .cs1-hidden-error{display:none;color:var(--color-error,#d33)}.mw-parser-output .cs1-visible-error{color:var(--color-error,#d33)}.mw-parser-output .cs1-maint{display:none;color:#085;margin-left:0.3em}.mw-parser-output .cs1-kern-left{padding-left:0.2em}.mw-parser-output .cs1-kern-right{padding-right:0.2em}.mw-parser-output .citation .mw-selflink{font-weight:inherit}@media screen{.mw-parser-output .cs1-format{font-size:95%}html.skin-theme-clientpref-night .mw-parser-output .cs1-maint{color:#18911f}}@media screen and (prefers-color-scheme:dark){html.skin-theme-clientpref-os .mw-parser-output .cs1-maint{color:#18911f}}</style><cite class="citation book cs1 cs1-prop-long-vol"><i>Title</i>.

Space characters between the assignment operator (the '=' sign) and the parameter value are not counted when calculating the position.</p> <p>Strip marker errors can also be caused by unsupported additional text or templates in parameter values—for example, <span class="nowrap">{{</span><a href="https://en-m-wikipedia-org.translate.goog/wiki/Template:ISBN?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Template:ISBN">ISBN</a><span class="nowrap">}}</span> in <code class="tpl-para" style="word-break:break-word;">|title=</code>. Resolve the problem by moving the extraneous text outside the citation template, or by removing the extraneous text or template markup, as appropriate.</p> <p>Pages with this error are automatically placed in <a href="https://en-m-wikipedia-org.translate.goog/wiki/Category:CS1_errors:_invisible_characters?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Category:CS1 errors: invisible characters">Category:CS1 errors: invisible characters</a> (4 pages).<sup id="cite_ref-categories_1-10" class="reference"><a href="https://en-m-wikipedia-org.translate.goog/wiki/Help:CS1_errors?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-categories-1"><span class="cite-bracket">[</span>a<span class="cite-bracket">]</span></a></sup></p> </section> <div class="mw-heading mw-heading2 ext-discussiontools-init-section section-heading" onclick="mfTempOpenSection(14)"> <span class="indicator mf-icon mf-icon-expand mf-icon--small"></span> <h2 id="Check_|arxiv=_value" data-mw-thread-id="h-Check_|arxiv=_value"><span id="Check_.7Carxiv.3D_value"></span><span data-mw-comment-start="" id="h-Check_|arxiv=_value"></span><span id="bad_arxiv">Check |arxiv= value</span><span data-mw-comment-end="h-Check_|arxiv=_value"></span></h2> </div> <section class="mf-section-14 collapsible-block" id="mf-section-14"> <div style="margin:.1em;

Because editors may be in time zones that are one day ahead of the UTC date, one extra day is accepted.</p> <p>Pages with this error are automatically placed in <a href="https://en-m-wikipedia-org.translate.goog/wiki/Category:CS1_errors:_dates?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Category:CS1 errors: dates">Category:CS1 errors: dates</a> (165 pages).<sup id="cite_ref-categories_1-17" class="reference"><a href="https://en-m-wikipedia-org.translate.goog/wiki/Help:CS1_errors?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-categories-1"><span class="cite-bracket">[</span>a<span class="cite-bracket">]</span></a></sup> <span class="anchor" id="Date_Fix_Table"></span><span class="anchor" id="Dates"></span><span class="anchor" id="DateFixTable"></span> <span class="anchor" id="ExamplesOfUnacceptableDates"></span></p> <table class="wikitable"> <caption> Examples of unacceptable dates and how to fix them </caption> <tbody> <tr> <th>Issue</th> <th>Unacceptable</th> <th>Acceptable</th> </tr> <tr> <td>Hyphen in date range (use en dash)</td> <td><code class="tpl-para" style="word-break:break-word;border: none;

The error occurs when the template produces wikilinked content. For example, <code>{{<a href="https://en-m-wikipedia-org.translate.goog/wiki/Template:Lang?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Template:Lang">lang</a>}}</code> templates output a wikilinked category.

As a general rule, avoid using templates in title-holding parameters unless you know that the template's effects are entirely visual (<code>{{<a href="https://en-m-wikipedia-org.translate.goog/wiki/Template:!?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Template:!">!</a>}}</code> and the like).</p> <p>This type of error may also occur in identifier-based templates (<code>{{<a href="https://en-m-wikipedia-org.translate.goog/wiki/Template:Cite_doi?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Template:Cite doi">cite doi</a>}}</code>, etc.). When this happens, the error message is shown in the article but the error is actually located in the identifier-based citation template.</p> <p>To resolve this error, remove wikilinks from title-holding parameters that are intended to be externally linked or remove the external URL, which will allow the internal wikilinks to work as expected. If the conflict is implicitly caused through auto-linking (see above), this can be disabled using <code class="tpl-para" style="word-break:break-word;">|title-link=none</code>. If wikilink-producing templates are important to the citation, move them out of the CS1 template but leave them inside the citation's <code class="nowrap" style=""><ref>...</ref></code> tags. Some of the functionality provided by templates may also be available through CS1 parameters.</p> <p>To resolve errors in identifier-based citation templates, the template must be edited to correct the error. Exercise caution when editing these templates because identifier-based citation templates are often used in multiple articles.</p> <p>Pages with this error are automatically placed in <a href="https://en-m-wikipedia-org.translate.goog/wiki/Category:CS1_errors:_URL%E2%80%93wikilink_conflict?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Category:CS1 errors: URL–wikilink conflict">Category:CS1 errors: URL–wikilink conflict</a> (1 page).<sup id="cite_ref-categories_1-79" class="reference"><a href="https://en-m-wikipedia-org.translate.goog/wiki/Help:CS1_errors?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB#cite_note-categories-1"><span class="cite-bracket">[</span>a<span class="cite-bracket">]</span></a></sup></p> </section> <div class="mw-heading mw-heading2 ext-discussiontools-init-section section-heading" onclick="mfTempOpenSection(82)"> <span class="indicator mf-icon mf-icon-expand mf-icon--small"></span> <h2 id="Vancouver_style_error" data-mw-thread-id="h-Vancouver_style_error"><span data-mw-comment-start="" id="h-Vancouver_style_error"></span><span id="vancouver">Vancouver style error</span><span data-mw-comment-end="h-Vancouver_style_error"></span></h2> </div> <section class="mf-section-82 collapsible-block" id="mf-section-82"> <div style="margin:.1em; float:right; border: 1px solid #aaa; padding: 2px; background-color:var(--background-color-neutral-subtle, #f8f9fa); color:inherit;"> <span typeof="mw:File"><a href="https://en-m-wikipedia-org.translate.goog/wiki/Wikipedia:Help_desk?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Wikipedia:Help desk"> <noscript> <img src="//upload.wikimedia.org/wikipedia/en/thumb/e/e0/Symbol_question.svg/20px-Symbol_question.svg.png" decoding="async" width="20" height="21" class="mw-file-element" data-file-width="180" data-file-height="185"> </noscript><span class="lazy-image-placeholder" style="width: 20px;height: 21px;" data-src="//upload.wikimedia.org/wikipedia/en/thumb/e/e0/Symbol_question.svg/20px-Symbol_question.svg.png" data-width="20" data-height="21" data-srcset="//upload.wikimedia.org/wikipedia/en/thumb/e/e0/Symbol_question.svg/30px-Symbol_question.svg.png 1.5x, //upload.wikimedia.org/wikipedia/en/thumb/e/e0/Symbol_question.svg/40px-Symbol_question.svg.png 2x" data-class="mw-file-element"> </span></a></span> <a href="https://en-m-wikipedia-org.translate.goog/wiki/Wikipedia:Help_desk?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Wikipedia:Help desk">Help desk</a> </div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1238218222"> <p><span class="citation-comment" style="color:#d33; font-size:120%">Vancouver style error: <type> in name <number></span></p> <p>This error is reported for citations that use <code class="tpl-para" style="word-break:break-word;">|vauthors=</code>, <code class="tpl-para" style="word-break:break-word;">|veditors=</code>, <code class="tpl-para" style="word-break:break-word;">|name-list-style=vanc</code>.</p> <p><a href="https://en-m-wikipedia-org.translate.goog/wiki/Vancouver_style?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" class="mw-redirect" title="Vancouver style">Vancouver style</a> restricts author or editor names to the Latin alphabet.
