The {{para|access-date}} (or its alias, {{para|accessdate}}) is the date that the online resource addressed by {{para|url}} was added to the article. If {{para|access-date}} has been included in the citation without {{para|url}} then this message appears. If the citation does not use a web link, then {{para|access-date}} is redundant and should be removed.

When the archive.org URL has any of these errors, Module:Citation/CS1 does not link to archive.org and emits an appropriate error message.

To resolve this error, choose the URL of an appropriate snapshot from those held at archive.org. [https://archive.org/web/ Search for the target URL].

{{para|archive-date}} (or its alias, {{para|archivedate}}), identifies the date that the web resource was archived.

To resolve invisible-character errors, remove or replace the identified character. Because these characters are mostly invisible, the error message identifies the character's position in the parameter value counted from the left. Space characters between the assignment operator (the '=' sign) and the parameter value are not counted. If you move through the citation with the arrow keys then the cursor may stand still once at an invisible character which can be removed with {{keypress|Delete}} or {{keypress|Backspace}}. If you copy-paste a string to the "Characters" field at https://r12a.github.io/app-conversion/ and click "View in UniView" then the position and name of all characters is shown.

To resolve strip marker errors, remove or replace the identified tag.  The error message identifies the strip marker's position in the parameter value counted from the left.  Space characters between the assignment operator (the '=' sign) and the parameter value are not counted.

Strip marker errors can also be caused by unsupported additional text or templates in parameter values{{mdash}}for example, {{tl|ISBN}} in {{para|title}}. Resolve the problem by moving the extraneous text outside of the citation template or by removing the extraneous text or template markup, as appropriate.

When {{cs1}} and {{cs2}} templates contain {{para|biorxiv}}, a test is done to see if the [[bioRxiv]] identifier has the proper form.  There are two valid forms:

: six numeric characters without punctuation or spaces.

:: {{para|biorxiv|yyyy.mm.dd.######v#}} where:

A common error is to include the bioRxiv ''URL'' (<code><nowiki>https://dx.doi.org/10.1101/</nowiki>{{red|&lt;{{var|BIORXIV>}}}}</code>), or the biorxiv ''DOI'' (<code>10.1101/{{red|&lt;{{var|BIORXIV>}}}}</code>).

The {{para|osti}} parameter is for the [[Office of Scientific and Technical Information]] (OSTI) identifier.

Over time, some parameters have become obsolete or unnecessary. When this happens, the parameters are identified as deprecated. Editors are encouraged to use other parameters that accomplish the same purpose as those that have been deprecated. The CS1|2 deprecated parameters are listed in the following table, along with recommended replacement parameters. Parameter names are case-sensitive. Editors should expect that support for deprecated parameters will be withdrawn.

Some [[Help:Template|templates]] will also cause this error if they are part of a title-holding parameter. The error occurs when the template produces wikilinked content. For example, {{tlx|lang}} templates output a wikilinked category. Templates in url-holding parameters may also corrupt the citation's [[WP:COinS|COinS]] metadata. As a general rule, avoid using templates in title-holding parameters unless you know that the template's effects are entirely visual ({{tlx|!}} and the like).

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 wikilink-producing templates are important to the citation, move them out of the CS1 template but leave them inside the citation's {{tag|ref}} tags. Some of the functionality provided by templates may also be available through CS1 parameters.

While normally correct, sometimes the names listed on a PMID page contain errors when the author surname has a lowercase [[nobiliary particle]].  For example, {{PMID|17726700}} lists Magnus von Knebel Doeberitz as Doeberitz Mv which is not correct.  This author's name should be listed as {{para|vauthors|von Knebel Doeberitz M}}.<ref>{{cite web |url=https://www.ncbi.nlm.nih.gov/books/NBK7282/box/A33081/ |title=Other surname rules |website=National Center for Biotechnology Information |date=2018-05-18}}</ref>

To resolve this error, Romanize author and editor names.<ref>{{cite book |author-last=Patrias |author-first=K. |editor-last=Wendling |editor-first=D. |location=Bethesda, MD, USA |publisher=National Library of Medicine |date=2007 |chapter=Names in non-roman alphabets or character-based languages |chapter-url=https://www.ncbi.nlm.nih.gov/books/NBK7258/box/A48818/ |title=Citing Medicine: The NLM Style Guide for Authors, Editors, and Publishers [Internet]. |edition=2nd}}</ref>  Romanizing can result in two-letter initials, for example, the Greek letter 'Θ' Romanizes to 'Th'.<ref>{{cite web |url=https://www.loc.gov/catdir/cpso/romanization/greek.pdf |title=Greek |website=Library of Congress}}</ref> When author names have this kind of initial, Module:Citation/CS1 can't know if this kind of initial is a typo or a legitimate Romanized character so it will emit the Vancouver error.  To suppress the error after determining that the two-character initial is correct and not a typo, treat the name as if it were a corporate name by wrapping it in [[Help:Citation_Style_1#Accept-this-as-written_markup|doubled parentheses]]: {{para|vauthors|...,  Tatarinov IuS, ...}} → {{para|vauthors|...,  ((Tatarinov IuS)), ...}}
