On the Plugins screen I have options to activate and deactivate plugins, but I no longer have the "Delete" option. I'm relatively sure the option appeared earlier.
Also, when I hover over "Plugins" on the admin menu I don't get the usual popup submenu showing "Install New / Add / Editor". And when I click the Plugins menu I don't see those submenu options either.
What's gone wrong?
FWIW, the client I'm working for is hosted at GoDaddy.
