Regarding the first error, it is caused by a hack inserting data with the same key. You should ask the modification author for help.
Regarding the second error, it seems that your MySQL server is down, check with your host.

Thanks a lot Dismounted for help.
should i chck all hacks step by step ? or
Can you tell me wich hack is ? (If possible)

Thanks

[Dismounted]

It's a hack related to referrers, that's all I know.

[Paul M]

Either a hack specific to referrers, or a generic stats hack.

Thanks again.
