Ok...
Good news...
I have enabled most of the plugins and it hasn't come back yet. Most of the essental features are all working again.
Most of the stuff not enabled at the moment were old features or features only the staff used. I am going to leave them off for now.
I got to run and head to the XL Center for Monday Night RAW.
But I am glad we are up to speed again.
The issue is one plug in has rogue code in it which inserts its own ads (which you cant see but you can see them loading at the bottom in your browser) the reason I was not seeing them was it only did this to certain usergroups.
If you notice anything strange please let me know.
PHEW!
