phpbb3 + CPG ucp error

[WaterRatj]

I have the following issue when trying to bridge coppermine and phpbb3:
when I filled in the bridging settings I get this error

"Forbidden
You don't have permission to access /ucp.php on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."

The bridge is not enabled - nothing for us to see.

Looks like mod_security or something similar doesn't like the URL. You should probably talk to your web host.
