Technical Glitches

Not sure what I did (but I must have done something..) but suddenly now most of the sidebar-----> isn't loading! Very frustrated about this as I'm not sure how to fix it. But, rest assured, those whose links are usually found there, you are still there, your button just isn't showing at the moment ...along with my RSS feed, categories, archives, and twitter button. Hmm. Suggestions welcome to what went wrong and how to fix it.

I've not touched the html, I stick to the default editor mode which is a lovely WYSIWYG program. Perhaps the problems on my host's end, they did just do some sort of upgrade last week. Argh. So, yes, any suggestions and I will love you for it (seriously, I'm a Taurus: that's all it takes. :D)
