Hmm... Well, I checked the error logs for your IP and don't see any errors for it. I've never seen a maintenance mode page - not sure we even have one? The only thing I can think is that for some reason the security system built in to our software thinks you're not supposed to be here. But for that, you should receive an error code. Can you take a screen shot of the maintenance mode page you're getting and either email it to me or post it here?
I wouldn't suggest logging out since I'm not positive what the source of the problem is - wouldn't want you to not get in from the computer either.
Can you browse the forum as a guest from your iPad?
Are you trying to use
www.foodallergysupport.com as the address or foodallergysupport.olicentral.com? Which ever one you're trying, try the other. Our domain name is a redirect to here - maybe the glitch is in the redirect or can be worked around using the redirect.
Also, if those still don't work, try typing foodallergysupport.olicentral.com/index.php in the address bar.
One thing I just discovered... If you type
www.foodallergysupport.olicentral.com it must do something different because when I just typed it on my computer it took me here, but didn't recognize me - showed me as a guest. Any of the other ways I mentioned above recognize me, just not if I put www before the olicentral one. I guess that's something else you could try.
