Ok, so now all the blogs I had on the side of my blog have disappeared! I've tried to add, but what do you do????? Help!!I don't know how to get them back again, they are there when I go in to the "links ' thingy, but how to get them on to the blog I don't know!!!

Ok, so now I have one of them back but where have all the others gone??(song coming on!)
