plugins.php "File not found."

Hi there,

I am getting the following error:

– when I go to the network plugins folder in my multi-site, there is a blank white screen saying “File not found”

– this page: http://www.domain.com/wp-admin/network/plugins.php

I’ve tried removing all the plugins from the plugins folder, with the view to putting them back in one by one (as I think it might possibly be a plugin update that caused it), but even when I remove all the plugin folders from /htdocs/main/wp-content/plugins, the page won’t load?!!!

Please help!

Cheers 🙂
