I'm using JF3 Maintenance Redirect on a couple of sites. It was working perfectly on one site, but I've just noticed it's not working any more? I haven't changed anything and have tried deleting the plugin and reactivating, but it keeps going to the live site - client will freak out if they see this! AAARGH, can anyone please help me?
ps. I am a newbie, so apologies if the problem is my doing!
