Thank you peg for those fixes... I am going to try disabling a few mods later..... but I really don't think that whats causing it because I have seen this issue before on vbclassifieds pro...... & Paul Sonny's HELP CENTER PRO .... where you create a prefix set and the dropdown nav is empty after creating it.... then when you go to enter something into it, that drop open is empty so you can't put anything into it. In this case its after creating the Prefix Set, then trying to enter a prefix into it.... which shows empty so you can't add one.
I wonder if I try reupping a few vb php files? I hate letting anyone but a select few onto the forbidden sites backend, I only allow Murat (vbtube) and you....
