My Blog is Broken

My reading list does not show up half the time.  I have to refresh the screen a couple of times before it shows back up.  Also, a couple of blogs is now "hidden"  on the reading list.  I have to click show hidden blogs.  Why are they hiding?  How did this happen and how do I fix it?  I can't find anything in settings.  I use to have the blogs from my reading list on the side bar for others to see.  A lot of those are missing and I don't know how to "fix" it. 

Anyone?

Bueler?
