Hi, this works for me, what version of Page Forms are you using? I think this is related to this bug: https://phabricator.wikimedia.org/T239023, which should be already fixed in the last version of Page Forms.

hi,
I am using PageForms 0.5.2 and mediawiki1.34. The solution you sent me not work. but I fixed by my own solution.

my solution works for me, but didn't consider downward compatibility issue, https://gerrit.wikimedia.org/r/#/c/mediawiki/extensions/PageForms/+/575006/1/libs/PF_wikieditor.js

What version of Page Forms are you running? I assume it's not 0.5.2.

Ran into the same problem. Using version PF 4.9.1 and MW 1.34 -- the patch works for me.

Change 575006 had a related patch set uploaded (by markahershberger; owner: markahershberger):
[mediawiki/extensions/PageForms@master] fix WikiEditor not showing in textarea when editor=wikieditor

https://gerrit.wikimedia.org/r/575006

What version(s) of MediaWiki is the current code not working with? And what versions of MediaWiki does this new version of the code work with?

MediaWiki 1.34+ ... 5e55aeed71 is what my branch says

The important change, though, is probably this one in WikiEditor: d23d096

Okay, so "editor=wikieditor" stopped working with the latest version of WikiEditor in August 2019, and then there was a change to MediaWiki in March 2020 that possibly made it worse. But does this new code work with older versions of WikiEditor and MediaWiki?

I don't know. I haven't tested it. But I doubt it.
