when adding campaign: Fatal error: Allowed memory size of 8388608

When I click to submit a new campaign, I get:

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 11 bytes) in /mysite/wp-admin/includes/template.php on line 224

I have tried different feeds, all with the same error.

Any ideas?
