Hello. For some time now I have been having the problem where all the sudden when I try to click on "edit source" or "Source Editor" while in Visual Editor, it does nothing, in fact nothing loads. Sometimes it will give you the prompt: Invalid response from server.
Also I have the problem where now whenever I try to save long written articles the article will start saving and then prompt with: "server didn't respond in time"
I have updated the response time to being longer than was before and it sometimes works but usually does not and just gives that prompt.
This is on Mediawiki 1.40 btw.
