I am despairing: my blog works fine, but I get an insufficient permission error, when I try to edit the values via the option panel.
It only works for the first time. After that I got this permission error.
What have I done to solve the problem:
1) changed the tabel prefix: removed the capital letters ... everything was fine except this plugin.
2) I have stored a ".htaccess" into the wp-admin/ folder ...
Can somebody help me to solve this problem?
