For a few months, right after we updated MediaWiki in early 2023, we faced an issue with the talk pages. Whenever we tried using the VisualEditor in the talk pages, we were given this nasty error:
[X6akA72QQzSDKWPFYEuVSAAAAAU] Exception caught: Conversion from 'html' to 'wikitext' was requested, but core's Parser only supports 'wikitext' to 'html' conversion
I'm glad to finally announce that this issue has been fixed and we are now able to use talk pages with Visual Editor again.
