Fatal Error – Can’t Do Anything – HELP!!

Hello:

“Fatal error: Cannot redeclare widget_adsense_init() (previously declared in /xxxx/.dddd/aaaaa/blogbypass.com/wp-content/plugins/adsense.php:19) in /xxxx/.dddd/aaaaa/blogbypass.com/wp-content/plugins/widgets/gadsense.php on line 97”

After I’ve installed several Adsense sidebar widgets, the baove error message is the one that I get when I try to access any part of my WordPress menu.

I can’t log-out, I can’t move off the “Plug-In Management Screen” to another part of the menu without getting that message – just that message on a white screen.

I’m stuck – please help!

Paul
