Blank Notifications? (Low Priority)

When viewing my notifications on my computer as well as my phone, I had a notification that I could not see. By that I mean it said I had a notification but when I clicked on the envelope, it displayed only the border bars and the dismiss all notifications button (sorry, did not think to screenshot it). I'm not sure what the notification was, but after attempting to check it on multiple devices and browsers with the same result, I dismissed all notifications. Is there a way to view past notifications? Also is there a way to search for LFG posts that you've posted to? Thanks! (Mac OS X 10.11.1, Opera 33.0.1990.115, Firefox 42.0, iOS 9.1)

Is the notifications envelope still pink for you or is it grey? If it is grey, you should be able to click on it and it will pull up old messages.  As for your 2nd question, you can find your replies to posts by going to your profile and clicking the "View Replies" button.  Does that help you out?

I dismissed it, so it doesn't have anything relevant to that time. It was just a notification, I believe, not a private message. When I click on my comments, none are displayed. When I click on my topics, only this topic is displayed despite having posted in many (still active) LFG posts.
