Hey, thanks a lot for the quick reply! :-) I figured the problem was that the plugin couldn’t hook to the server heartbeat — in the settings, last heartbeat always said n/a –, so I tried it an a different server and everything worked as expected.
So it’s most probably just a problem with the server; I’ll ask the admins next week and report back.
Thanks for sharing this plugin BTW, very useful indeed! :-)
