Javascript stopped working

[Paul.F]

This is a weird one.

I have a vps with ubuntu 14.04 installed with a plesk cpanel.

Everything was running fine, and with no server changes or website change Javascript decided to stop working. ie. When I try to access the block on the front page via the arrow on the left (Using pages) I get "Couldn't get list of available blocks". Nothing that requires js seems to be working.

Went through the support in the admin panel and cleared te cache, changed the theme, disabled the plugins. Nothing seems to have fixed it. Even cleared my browser cache.

Anyone encountered this? I am at my wits end.
