If you receive the infamous “Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 131072 bytes) in…” error and a reference to a file in your wordpress installation, telling you that in one of your files there might be an error that is eating up your memory, and after having spent an hour or two on the not too friendly wordpress forums, trying to find a solution to no avail, then you might try this very simple solution: deactivate your latest plugin.
That’s right ! Whatever the latest plugin is in your wordpress installation, if the error was not there before installing and activating the plugin, then it would simply make sense, that it’s that plugin, which you installed and activated the latest, that is causing the trouble !
In my case, it was the much tauted and in my humble opinion, not so useful WordPress SEO plugin. The moment I’ve deactivated the plugin, the errors have disappeared. I’ve previously tried increasing the memory limit even to 128 MB (!), but the error was still there.
Now, that I’ve deactivated the plugin, everything works just fine.
