Hi,
I have a blog with 1500 pages. Some of them (5%) give Allowed memory size of bytes exhausted error (they are still loaded though). The thing is, if I copy the content of one of those pages and paste it in a new page with the same settings (parent category, template e.t.c) it works fine.
The error is on wp-includes/functions.php on line 434 :
retu serialize( $data );
Is there any way to trace the problem? I suspect it has something to do with the metadata of those pages.
p.s: the error is ONLY when logged in as admin (the admin bar is blank)
