Couldn't access admin cp neither, it's just blank with these warnings on the page.

Any help would be appreciated!

Anybody please help! It's emergency! I can't even log in the admincp to turn on the board! Everything is inaccessible to the audience and the search engine!

I just upgraded my PHP from 5.2 to 5.4 and it's fine. For anyone who's getting this should try this approach.
