There was a major bug with the signature plugin a while ago but AFAIK they fixed that, I’m not going to try it now, won’t be popular if I crash the forum.
I’m really surprised adding html worked, I didn’t expect it to.
Due to the security risk that was discovered last night, we have disabled signatures for the time being. We will re-enable them again once we have a safe and secure way for them to be included. Thank you for your patience.
The sizing is a little different which is annoying. Probably better than the original plugin on here that let signatures extend past the boundary of the post.
Had a play with the style and managed to get the text a nice Black to mix in with my theme as well as increase the default font size. That tiny light grey is far to hard to easily read (IMO).
