Going to https://www.wikidot.com/account/activity often doesn't work. It won't load the new comments, or it will load one page and fail to load more. Sometimes I can't check my account activity for days on end, that's nothing new.
Over the last two days, though, I haven't been able to check my activity at all. All that shows up is "An error occurred when processing your request." I once got it to give me the "couldn't load comments" popup (I forget exactly what that one says), but it went right back to "An error occurred when processing your request."
I am using Chrome and haven't made any changes to my ad blockers or NoScript recently
