Error 403 on Opencart

Hello.
Who can faced a problem on Opencart. When I try to save changes in the settings of the modules or template, I get an error:

Forbidden
You don't have permission to access /admin/index.php on this server.

Fix Permissions does not help.
The files have 644 permissions, and 755 on folders.

It only helps to disable ModSecurity for the domain.
I use Comodo WAF

The last entry in the domain.com.error.log file:

Code: [Select]

Is it possible to fix this somehow without resorting to disabling ModSecurity?
Thank you in advance.

Здравствуйте.
Может кто сталкивался с проблемой на Opencart. При попытки сохранить изменения в настройках модулей или шаблона получаю ошибку:

Forbidden
You don't have permission to access /admin/index.php on this server.

Fix Permissions не помогает.
На файлах выставлены права 644, а на папках 755.

Помогает только отключение ModSecurity для домена.
Использую Comodo WAF
Можно-ли это как то исправить не прибегая к отключению  ModSecurity?
Заранее спасибо.

rule id 211290

Correct, added the rule 211290 and website backed to normal. Thank you
