Maximum execution time of 60 seconds exceeded

Hi,

I am getting a few errors when trying to change a node permission for the 'registered' user group. E.g I wanted to revoke the permission to vote on polls for this group on a certain node and the error occured. The actual errors are almost the same.

Spoiler: First error
