Manager/ Blank page

Hello,

I was doing some snippet executing a DB query via AJAX. Nothing seemed to trouble my site, when i went to switch to another resource and I noticed that the [site]/manager/ path was generating a blank page.

The site itself is working as before, the problem is that I can not get into the Manager section any more.

Did anyone experience such strange things?
