Need help with Subscriptions

I am not getting messages left at any of the Threads I created and when I check my subscriptions under "Settings" each subscription is set to "daily by e-mail" but the box next to each is not checked. I can check the boxes and go to the next page but when I go back to previous pages the boxes have gone back to being unchecked. Which I assume is why I’m not getting notifications. What do I need to do to ensure I get any message left in a Thread?
Thanks!

That Feature isn’t avaible anymore since the last few Hacking Attempts, sorry.

No more Notifications.

It was nuked just like the "like" system. Totally sucks.

Sorry—I probably should have known that!

my subscription to game informer doesn’t show up in the mail anymore. can anyone help
