Yeah, I’ve got the same thing happening. The field shows up in profile edit, but when I enclose the image url with the bbcode and save, there is no sig in the profile. Then, when I go to edit it again, the url is there, but the bbcode has been removed.
Edit: I’m working with WordPress 3.8.1, bbPress 2.5.3 and BuddyPress 1.9.2 (all the most recently updated versions).
Edit x2: just posted and it is showing under my post, just not in profile field.
Same deal. Signatures fully work and display on the forums, but it’s a bit iffy when updating them through BuddyPress profiles. Saving bbCode — anything from links to images — works and will display in your forum signature. But going back to BuddyPress to edit again, the field is either left blank or shows the raw HTML. Saving with the raw HTML will, of course, be stripped if you have signatures set to bbCode.
Looking at the signature field through wp-admin displays as intended.
And a suggestion on this topic: have an option to allow both bbCode and HTML usable, without stripping either of the two.
