I have the same issue with a WP multisite I’m working on.
Everything was working fine until yesterday. Now the front-end works as before, but the backend takes like 10 secs to load every time.
I’ve tried deactivating all plugins and adding define(‘WP_MEMORY_LIMIT’, ‘512M’); (and other values as well) to wp-config, but neither seems to work.
I don’t remember exactly what I’ve done before it stopped working. I’ve had an update recently (to 3.4.2), added some plugins, changed the max upload file size value (which I tried changing back) and other stuff…
Any ideas ?
I also tried to insert
query_posts(array('paged' => 1 ));
before calling the loop file in index.php, but no posts at all were shown.
