Is it enough just to create the page [[MediaWiki:Uploadtext]] to have it's content
displayed on [[Special:Upload]]?
I ask because I encountered such a problem on a non-WMF wiki.
[[MediaWiki:Uploadtext]] was created with a custom content, but
[[Special:Upload]] remains intact, unchanged. This happened on Wargaming Wiki -
need probably to create an account there to check this yourself. But you can see also
this short video I've recorded, which is demonstrating the issue:
(I tried to attach it to a mail but there
appeared problems with the size of mail+attachment).
Can someone tell me what's wrong here and how it can be debugged?
Thank you in advance.
