[RESOLVED] Activation problem VTE 4.4.1

Completed the installation without problems activation procedure ' crm.domain.it/modules/Morphsuit/RequestM...ph_mode=installation ' return the error 403 Forbidden - Access to this resource on the server is denied!.
Folder modules/Morphsuit permissions are recursively 777.
Have you any suggestions?
Thank you.

Folders and files setting with cpanel file manager is difficult. I set the permissions with the command line and it worked. I can not imagine to use any hosting service without the command line! Here are the commands:
find . -type d -exec chmod 755 {} \;
find . -type f -exec chmod 644 {} \;
