Can't set signature or about page.

[Cookie]

I am new to this forum, and familiar with this forum software
I have never encountered this problem:

When I try changing my About and Signature, it says

I was trying to set my About as:
I love Tech and Coding!

and my signature as
I love TECH and CODING

Welcome aboard @Cookie - there's a spam filter on the signature box for the first 10 posts or so. It might be worth coming back to edit the signature in after a few posts to see if that works ok? We get a lot of members signing up to add links to their sig, so we've had to put anti-spam software in place.
