Can't seem to update profile pic anymore

Whatever I add to "I have my own pic" under forum profile information, and clicking 'change profile', profile just reloads to no image being used. I tried putting it on imgur, it doesn't accept either of these urls:

https://imgur.com/VGD6efn

even though I see other profiles sometimes using this exact host and url format. I've also tried re-adding the old one I was using:

https://nearworlds.org/stuff/octo.gif

which it doesn't accept either, even though I'd previously been using this exact url for several years, including five minutes ago before I tried to change it.

I don't see what the problem could be. Concerned

Is forum software buggy lately? Am I buggy? Shocked

EDIT: Sorry, for some reason I missed the sticky. Feel free to delete this thread and I can repost in there.

100x100 doesn't work either:

Neither does removing the s:

EDIT 2: nevermind, it just updated after I posted in the other thread. it was just really really delayed.
