MW Accessibility Checker flags article-level WCAG issues

Accessibility issues arise because Joomla sites often depend on authors to supply meaningful image text, logical headings, labelled fields and usable links. Joomla core provides the editor and fields needed to enter much of this information, and a template override can improve the markup a component outputs. Core does not, however, provide an article-level WCAG score, a catalogue of content problems, automatic checks on save or a general-purpose correction workflow. According to the listing, this extension goes beyond those facilities with more than 13 checks, fix previews, undo before saving and an option to block saving when critical errors are found.

It is aimed at teams publishing substantial volumes of editorial content, especially where several authors need a consistent pre-publication check. A small site with a careful author, a bespoke accessibility review process or no accessibility requirements beyond its existing template is less likely to need it. It will not replace testing the finished site, its template, forms, navigation or third-party output.

The directory marks the download as free, but the listing describes a premium backend component and a seven-day free trial; it does not state the premium price or what remains available without it. Mertsch-Web is shown with nine other extensions in the directory, but the listing gives no useful track record or review history for this product: reviews are at zero. Check the Joomla compatibility claim carefully: the text says Joomla 6.x and PHP 8.2+, while the compatibility field also shows J5 (backend/plugin) and J6. The listing also leaves unanswered how accurate the auto-fixes are, which WCAG version and success criteria are covered, and what happens with custom editors or HTML.
