Memory Limit when logged in as 'Editor'

Love this plugin, used it many times before without error until now. When activated and using the Admin login, no problems. When the client logs in (Editor, not Admin), if they click Pages menu to edit pages, they get this error:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 122880 bytes) in /public_html/wp-admin/menu-header.php on line 98

There are 88 pages and only 5 posts. Posts open just fine but not pages, so I’m assuming it has something to do with the amount of pages? Anyway, is there something I’m missing or need to do?

More info: I’m using the plugin to add a logo as a link to the home page as well as disable all other admin tools in the bar except for the ‘+ New” button. If I deactivate the plugin and log back into the Editor’s account, the error goes away.
