Widget not found error on pages I don't have permission to access
Closed, ResolvedPublic

Description

When I visit https://www.mediawiki.org/wiki/Special:CreateMassMessageList when I don't have permission to view the page I see the error "Uncaught Error: Widget not found"

This is understandable as there is no widget on the page

Also occurs on action=delete and Special:GlobalPreferences presumably for other reasons.

Needs better URL or description if the user has some rights or not, the case for Special:GlobalPreferences and Special:Preferences could have the same cause, there are very similar

https://commons.wikimedia.org/wiki/Special:Preferences redirects to Special:UserLogin, not sure how that should happen.

Maybe it is better to get own task for separate issues, at least when there are other reasons to fail.

The MassMessage part should be fixed.

Jdlrobson claimed this task.

Sounds good. I'll open new bugs.
