im running nuke 7.6 (clan nuke) and im getting this error when i try to insert an avatar into my profile which is on the server (not linked).

has any1 any clue why its doin this and how to fix it????

If memory serves me correctly, this error means your theme wasn't ported properly. That isn't to say this is the ONLY problem, but the answer I seem to remember.

If you are using one of nukemods themes, I doubt this is the case, but if not, you may want to look around and see if there is another port for the theme somewhere.

Another step would be to re-upload your theme again.
