Where did you add that emilbus20?
Because stll after a new install of WP
I still get wp-admin/themes.php?page=widgets.php
in the Appearance – Widgets instead of wp-admin/widgets.php
I could fix this but I have no idea which file needs to be fixed.
I checked all three widgets.php and they seem to be correct!
This is a real pain…. I deal with multiple blogs and can’t seem to find the soloution. (I’m using FireFox and tried IE same issue)
