I'm building a CMS for a company that has 60,000+ static pages which have been converted into posts. 30,000 of these are a particular post type. When I try to access the edit screen in the admin area (http://www.mysite.com/wp-admin/edit.php?post_type=post-type.
On my local server I get an internal 500 error.
On my live site, (database migrated with wp-migrate-db-pro) i get:
Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 71 bytes) in /home/omol/public_html/wp-includes/post.php on line 1876
seems like 256m should be enough memory? I wasn't having this error before and was able to see the 30,000 articles on the edit screen just yesterday.
I've reverted to twenty-twelve theme & checked the htaccess, to no avail.
