I can't get into /wp-admin because this error comes up
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 491520 bytes) in /home/.../public_html/wp-content/plugins/nextgen-gallery/admin/manage-images.php on line 481
I was getting a similar error yesterday while trying to set up a photos page, but it never caused a problem that stopped me getting in. I've got in today once before this error popped up. It's clearly a problem with nextgen-gallery but how do I get it cleared (I need to delete the plugin eventually I reckon)?
