For some reason when ever I edit my signature, it doesn't parse the BB code.
As you can see in the picture above.
do you have "MyCode is On" at the left bottom (below Smilies are On) ?
related setting is here : admin panel --> configuration --> settings --> User Registration and Profile
Options --> Allow MyCode in Signatures <-- select yes & save settings
Thank you, that did the job.
I wonder why it was off, weird.
