I've been trying since January to edit my signature and I get this error message: TypeError: Unsupported operand types: string + int in ..../includes/class_sigparser_char.php on line 295

Any idea what it means? Even if I go in to edit and don't change anything, I still get that same error in "preview signature" as well as "save signature".

I think that's an error related to this, that will need to be fixed by IB's coders.

Unfortunately, we no longer support different font colors or sizes in signatures

Is that actually what's causing Surfinhank's error? Unsupported functionality probably shouldn't be included in the signature editor and it certainly shouldn't result in a cryptic PHP error that doesn't indicate the actual problem.

FWIW I can still change the font color in my signature without a problem...

I didn't have any colors but I did have 3 size tags of "plus 2". I removed those and it's working fine now. Thanks for the help!
