My WordPress blog has been working fine for almost five months now. Then all of the sudden a couple of days ago it stopped. Now everytime I try to load a file it tells me "File of type is not allowed." But that's not true. When I go into my Options for file uploads, it has the same settings its always had. The file types I've been trying to load (jpegs) are the same file types I've been using all along. Nothing has changed in the settings, but it just won't upload the files anymore.
