I am getting an Access denied with code 403 when I try to update or delete Leads. My log files have this error in it:

[Sat Nov 03 10:44:32 2007] [error] [client 71.110.202.177] mod_security: Access denied with code 403. Pattern match "((alter|create|drop)[[:space:]]+(column|database|procedure|table)|delete[[:space:]]+from|update.+set.+=)" at POST_PAYLOAD [id "300015"] [rev "1"] [msg "Generic SQL injection protection"] [severity "CRITICAL"] [hostname "mydomain.com"] [uri "/index.php"]

I am not hosting this site myself. What do I need to do and what should I tell my hosting company to do?

Thanks,

Warren
