By enabling mod_security with OWASP rules, you should also test your websites fully and if you get forbidden 403 or similar error messages then you would need to check which OWASP rule is blocking you.
You can check the rule ID blocking you by simply searching your IP address in the mod_security module of the CWP.
To disable a rule blocking you, you need to add its ID listed under quotes into disabled rules file and once you add all rules the apache reload is necessary to accept this new changes.
