I upgraded Tao from 1.0 to 3.2 (to support Rubik as an admin theme) and after clearing the cache several times, I'm still get this error on every page:
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'tao_form_element' was given in theme() (line 656 of [root]/includes/theme.inc).
Effect is all checkboxes have disappeared from the backend.
There doesn't seem to be a
tao_form_element... anyone else getting this?
