I couldn't find any boards for this, so if there's one already and if it's not happening to anyone besides me, I apologize.
But it's been at least two weeks since I try almost everyday to update my forum signature and it never works, and the MySQL Errors show. I can provide a screenshot with the page's link and the error if needed. is this happening to anyone else? 8c
OK SO I removed it completely and it worked, but it won't let me add the old one back. I tried something simple and it worked, but when I used sCode the error popped up so maybe the issue is with sCode?

I've been having the same problem - running Chrome on Windows 8, if that helps anything.
(I'm running Chrome on Windows 10)
This happened to me tonight when trying to input a few lines into a pet friend's text. So not a forum signature, but it is essentially a signature?
It would let me put parts of the text in, yet every time I tried to put in "Let's" it would give me the squirrel error. (Curiously, if I put in "I'm" it allowed it, so I don't think it was the apostrophe, but who knows...)

I've been having this issue for a month now. It won't allow me to change my forum image, although it did let me remove it. I am incredibly frustrated that even the simplest things on this site don't work reliably.

Hey guys, this should work now! If you have any issues let me know.
I'm gonna test it in a few minutes but if you said it's done then it's done. 8) thanks a bunch!!

I'm still getting the error :/ I can remove but it won't let me add anything I tried both on chrome and firefox
