Plugins won't install or uninstall

Ok so I try to uninstall or install plugins and I click them and they change to “uninstalling” but never do. The page reloads and never uninstalls. Can I please get some assistance here?
Can you install and uninstall plugins via command line? I’m not talking about the box install command. Talking about plugins

Since I am trying this in a testing environment I am willing to give out SSH access for someone to look at it and let me know a way to solve it in the future.

Thank you

Sigh. I wanted to pay for quickbox pro but is suppose any better than this?

-.- Sigh still haven’t got this working.
