Fatal Error on Product Listing in admin area

Hi All,

Now I am not sure if this if the right place for this one but I only get the error accessing the product listing page in the admin area, but only one (mine) administrator profile?? Logging out and logging in with the other administrator profile is fine.

So I thought to ask here first.

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 82 bytes) in /home/.../public_html/wp-includes/wp-db.php on line 1545
