406 Not Acceptable Errors

Problem

While working with product provisioning, you see the following error:

406 Not Acceptable

Cause

This error is usually due to the server’s mod_security rules blocking the query from WHMCS.

Solution

To resolve this, check the mod_security log for the triggered rule and that rule.

If you do not have access to the server’s mod_security log or to change the rule configuration, contact your server administrator or hosting provider.
