This blog hasn't got anything to do with updates and stuff.

As for your problem, check the following:
 * Describe exactly what you're trying to do that doesn't work. Did it work in the past?
 * Which editor do you use? Visual, Old or Source?
 * Which browser do you use? (and, does the problem exist on other browsers?)
 * Do you get any error message?
 * Can you upload images via Special:Upload?

Check these, and then use Special:Contact/bug to send in a bug report. Even if it does work on a different browser, or in a different uploader or editor, it should work on all, so it's still a bug.
