In the settings page, there are no options with a tick. When trying to tick anything the cursor becomes a "hand" BUT clicking does nothing (actually clicking seems to just select a white space inside the box).
Also the first of the 3 buttons in the bottom is white.(the other two are "Update Settings" and "Delete RSS data"
Tried to un-install and re-install the plugin, nothing changed.
PS Renaming database prefixes went smoothly, other than that site is working OK. WordPress is 3.8, plugin is 4.03
