Running into an error on Cohost, as it is currently, provides very little information about the difference between "you just switched pages while looking at follow requests" and "the site is down." In fact, I'm pretty sure the only error that's clearly different is a 404.
As well, there are no buttons on the page except "log out" (which in my experience has never been the fix for the problem) and "go home."
I think the sidebar should show up on error pages, and the log out button should be deprioritized or even moved to link text instead of an enticing button.
This is more of a "stubbed toe" than anything, but it's annoyed me enough times that I figured I'd mention it as something I'd like to have looked at eventually.
