Thread:Extension talk:Spoilers/Spoiler-Button instantly disappears (although it is shown for a spöit second)/reply (4)

I think I have same problem with MediaWiki 1.24.2. There is something like a spoiler for a moment but then it disappears.

Using it like this also causes these errors: while using just shows nothing.

Please update extension OR release status, because it is probably not stable with modern versions.
