Notifications not working any more.

Originally I am sure I got notifications when there were replies to my posts.

Recently I am not getting any.

The "Notify me of replies" is ticked and I have not changed it to anything else.
As I used to get them I am not sure what to do than ask if anyone knows.

(P.S. Notify ticked)

Along with problem is one related that I just found. I was getting email notifications for replies to a forum item, but I decided to discontinue the notifications. I clicked the link to stop the notifications and was taken to the forum entries, but the tick for email never changed. Later, I had to manually stop the email notifications.
