Hi greggles,

Sorry for that english!!!! :D

Maxipoint help desk already responded my question. Here is the answer:

Hello,

As I see your scripts require too much system resources. Please consider to upgrade the account to own VPS or dedicated server. Or try re-write your scripts better.. using 12% of CPU by so strong server say me that your scripts do something wrongly.. this is high CPU using if you have own server for your one domain only!

As you can see, their answer is, take our VPS service, or die!!!! I dont have the knowledge to re-write the scripts!!!!!! I dont know what to do.....

When I wrote "some times, some pages" I was refering that sometimes, when I tryed to login, the error shows! not always, the same if I browse any of the pages that I have uploaded. Not always happens to the same page.

I´m still trying to get some answers on google.....
