Default Play Store 'Server Error'

So Today I got my note 3, rooted it using CF-Auto-Root and everything is/was working like normal.
However, now, after 10 hours I get 'server error' whenever I try to access the play store. Everything else works just fine. E.g Chrome, Instagram, YouTube etc etc.
I've tried to wipe the cache but nothing I've tried has worked.

Any help would be appreciated.

EDIT: Works fine on 4G. I just tried restarting my router but that didn't work either.

EDIT 2: I fixed it.
Since I was using Adblock+ before I was rooted, I had to put in a proxy. Removed it and now everything works perfectly.
