trying to update from WordPress 3.1.1 to 3.2.1, with site network activated (2 sites) I get the same kind of error :
Fatal error: Out of memory (allocated 30932992) (tried to allocate 4580905 bytes) in /homepages/##/######/htdocs/wp-includes/class-http.php on line 1426
Tried all the fixes like:
- deactivated all plugins
- added the line to wp-config.php to up the memory limit.
- even cleaned the database by removing all revisions of pages and posts (thanks to "Revision diet" plugin)
Did not do the trick, I cannot get wordpress to update and I get the exact same error every time. any clue?
by the way, is it really a php memory error? I have noticed that WordPress gives me "Php fatal error" in other cases (that are now solved), in this case it's only "fatal error".
