DeeAnna, what happens if you click directly on your screen name, or the number right next to your screen name?
This is what always happens for me when I do so: a small 2-toned green box will pop up right underneath my screen name. The top part of the box is a dark green color, and it says "Notifications". The bottom part of the small box is a lighter green color, and if anyone has recently PM'd me, and/or 'liked' any of my posts, and/or quoted me, it will show up in that lighter green box.
For example, if someone recently liked one of my posts, the light green part of the box under 'Notifications' will say, 'New Likes" with a number next to it of how many new likes I have. If I click on it, it will list out the latest of my posts that people have recently liked, and also list the names of those who liked them........well, at least that's what should
Starting yesterday and continuing on into today, I keep getting a 404 error message when I click on 'New Likes'. Interestingly, though, I'm still able to see my PMs and also whoever quoted me, but it's driving a bit batty because I have 9 'New Likes' and can't 'see' them.
