I am moving my IPS 4.7.2 to another server. This error is displayed

Forbidden

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

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

 

Backup the database
Copy the files /forum to a new server
I restored the database
Modified conf_global.php file with new BD values

Any help or idea .. ??

Thank you very much..

Linux? Make sure your permissions are set up correctly, right apache or nginx user.  If using SELinux, there are more details to worry about. 

If you used FURLS, make sure your php configuration has AllowOverride set to All so you can set up your .htaccess rules. 

The .htaccess files generated a conflict on the new server. The accesses were modified.
