Can not enable plug-in

Access denied? That’s the first time I’ve ever seen that.

I suggest you completely remove the plugin from disk using perhaps FTP and then reinstalling.

Still not work

Still says access denied? There is absolutely nothing in Broadcast that has that text string.

In fact, not even PHP has that text string. The real error message must be somewhere else. The question is: where? Nothing in the server errors logs?

It just happen when I try to enable the plug-in

Without more information than that I can’t help you.
