s2members probreaks admin pages

A recent update of something rendered the admin area to site useless. We have recreated the whole site on a new server, reinstalled all plugins and everything works fine. We have updated to the latest wordpress and buddypress but when we activate s2members pro we can no longer access the pages in the admin area. All the pages with capabilities have been imported from the last site as there a few hundred pages with separate capabilities. I think this may be issue. in debug i get this error

Notice: Undefined variable: cache_needs_updating in /home/audio2/public_html/wp-content/plugins/s2member/includes/classes/cache.inc.php on line 97 Notice: load_plugin_textdomain was called with an argument that is deprecated since version 2.7 with no alternative available. in /home/audio2/public_html/wp-includes/functions.php on line 3553 Fatal error: Out of memory (allocated 61341696) (tried to allocate 79 bytes) in /home/audio2/public_html/wp-includes/wp-db.php on line 1402

Does any one have any ideas?

Hi there. Thanks for your inquiry.

Nothing jumping right out at me that’s related specifically to s2Member. Notices in DEBUG mode are to be expected. Current versions of s2Member are not designed to run in full DEBUG mode yet. See this article please: http://www.primothemes.com/forums/viewtopic.php?f=36&t=2692

I do see that you’re running out of memory. It looks like you’re hitting the current limit of 64MB. Have you tried raising that limit yet? See this article please: http://codex.wordpress.org/Editing_wp-config.php#Increasing_memory_allocated_to_PHP
