Switched vB to new server, now getting error updating plugin

We had to move our forum to a new hosting provider/server this week.

I just discovered a new glitch since the move, and I'm not sure where to start looking to solve it.

I can access the edit form for my plug-in in the Admin CP, but when I try to save it, I get this error:

Forbidden
You don't have permission to access /forum/admincp/plugin.php on this server.

Apache/1.3.39 Server at [domain] Port 80

This is a plug-in I had made which was working fine on the old server, and there were obviously no issues editing/saving it.

Can anyone suggest where I should look to fix this?

I'd ask your host

Will do. Thanks. Wasn't sure if it was something I could fix on my own.

[Brandon Sheley]

Well, I would start with the host, then move on the this forum.

it seems like a permission error, most the time when you see "forbidden" it's a host issue

[vbem2]

It was a firewall setting, according to the host. It's working now.

Thanks for the prod in the right direction on this, Loco!
