I have attempted to save a change on the Add html/css inserts section and it defaults to the blog with the error message in the Title of "Nothing found for Wp-admin Themes Php?page=functions Php&saved=true"
I deactivated all the plugins but error is still there.
I started out with 3.4.9 and reverted to 3.4.4 and still the same issue.
I then went up to 3.5.1 and I still have the same problem.
Thanks for your help.
