ask your hosting provider for help

Well,
This is my home-operated server!

This is a message generated by phpids, its a script that detects attacks on your website. As for the current error on the website, it looks like the cache is corrupted or something, usually deleting cache files solve these kind of errors. I don't see a real hacking attempt in this report, but I may overlook something. Not sure what's going on. If the cache became like this since those attack reports you would think they might have done something..

I tried to delete the cache files, but that did not solve the problem. I have someone working on it for me. I hope it wil be solved soon. Thank you so much for your help!!!
