Topic on Extension talk:CIForms

I currently have the 1.39 package for CI Forms running on MediaWiki 1.41. I've had this issue even when MediaWiki was at version 1.39. Basically when I load the pages Special:CIFormsManage or Special:SpecialPages, I get the following errors:

[562694b55f00e86faf703aa2] /index.php/Special:CIFormsManage Error: Class "MediaWiki\Navigation\PrevNextNavigationRenderer" not found Backtrace: from /var/www/html/extensions/CIForms/includes/specials/PrevNextNavigationRendererCIForms.php(24)

12. 11 /var/www/html/index.php(46): wfIndexMain()
13. 12 {main}

Not sure how to resolve this as no forums online seem to address this issue. Any help would be appreciated.

@Tarunjoseph93 since MW 1.41 the class PrevNextNavigationRenderer has been removed, as a consequence CIForms is not currently compatible with MW 1.41. I have scheduled to do a general maintenance of the extension, but I don't have yet an ETA. If you need urgent support you can contact me by email

Does this mean I need to revert my MW version to 1.40 or 1.39?

unless you can/want disable CIForms, yes
