Topic on Extension talk:WikiForum

Install went smoothly, and set-up went well, until I tried to actuall post a topic:

[Yl3RvajgvwANJiXOLIwiDAAA5gQ] /index.php?title=Special:WikiForum&wfaction=addthread&forum=3 InvalidArgumentException: WikiPage constructed on a Title that cannot exist as a page: Special:WikiForum

Can you provide more information about your setup, e.g. MediaWiki version? The exception message ("WikiPage constructed on a Title that cannot exist as a page") seems to not even exist in MediaWiki 1.35, the current LTS release, which is what WikiForum has been currently tested with and somewhat guaranteed to work (as per social tools/MediaWiki compatibility, which basically applies to all other extensions and skins I also maintain). I tested out both topic creation and replying to an existing topic on my local 1.35 install and both worked just fine.

It's unfortunate, though hardly surprising, that things break with newer versions of MediaWiki, especially as the powers that be intentionally make breaking changes to the underlying APIs. I cannot promise anything else than to take a look, but the guaranteed fix is to use a compatible (LTS) version of MediaWiki core, i.e. the 1.35 series currently.

Thank you Jack. This is from my "version" special page:
