Just updated to version 3.1. Reactivated WP Download Monitor (most recent version) and it breaks the site.
I see this error message in the widgets portion of my themed site.
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 71 bytes) in ???/public_html/wp-includes/taxonomy.php on line 2752
I added the ??? for security reasons.
