No I don’t think we were hacked.
I think it is a mySQL database issue. I checked the server’s own modification times going back hundreds of hours with a command line scan and no files were modified other than new userpic uploads.
The PHP logs have no new errors there
So I think a stylesheet file that the database used to tell Drupal to load is not being loaded
But I am working 7 days a week last 16 days so no time to work on it
So have these tits and I will work more when I can.
