XF 2.2 Install Add-on permission problem

[supapower]

Hello there,

I'm trying to upload a add-on to my forum but whenever I try to do it, this message pops up;

Forbidden​

You don't have permission to access this resource.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

What should I do?

That's a server issue.

Contact your host and they should be able to resolve it.
