Arrgh! Can't install new plugins!
For some reason, although I upload new plugins to the plugins directory, they don't show up on the 'Manage Plugins' page. If I remove one, it's gone, but others I have added don't show up at all.
This started because I want to install ProxyConnect. I uploaded it according to the instructions and couldn't see it. Then I tried uploading DiscussionPolls, and I can't see that either.
Am I doing something wrong?
