This is getting annoying

Ok, so, I'm having a HUGE glitch with my blog. I came on the other day to find all my widgets & stuff, that are normally on the right side of the blog, down underneath all the postings. The only time I can see them is when I just go onto one posting, but looking at the blog as a whole, not where they're supposed to be. I haven't done anything different to my blog this week, but it decides that it wants to get all wonky on me. UGH!!
