Fatal error in the plugin.php file in the /data folder

Good afternoon,

I have been getting this error off and on during the making of my wordpress site for a client and now the error below locks me out of the admin functions. Oy vey.

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 30720 bytes) in /data/20/1/105/93/1920256/user/2091693/htdocs/wp-admin/includes/plugin.php on line 240

I have tried to add more memory to the config.php file but no dice. I have a shopping cart plugin wp-ecommerce, contact me form and a “The The …” image scroller thing.

Anyone one else get an error like this? Or can a guru point me in the right direction for a fix or provide a fix?

Thanks for any help!
