I'm having the same problem. I'll see if I can explain a little more clearly.
1. J 1.0.15, CB 1.2RC2, FB 1.0.4
2. Click the link to edit your profile
3. Try to add a forum signature
4. When you click "save", nothing saves and the signature does not show up in the forum.
5. I have another install on J 1.0.14, CB 1.1 and FB 1.0.4 that works just fine.
6. After running the CB plugins check, I get the following response: CB plugin "CB Fireboard Plugin": no database or no database description.
That appears to be the issue. I'm also "not" using the cb.cimpleboardtab plugin. I'm using cb.fireboard plugin. Again, this is probably the problem.
Hope this helps. I'm going to try the simpleboard tab to see if that makes a difference.
