Hi t-p, thanks for the info. I hadn’t thought to manually update because I’ve never done it before. I decided to manually update my plugins first and that worked well. In fact, I am wondering if the problem was not caused by a plugin issue, because after I had finished doing that everything began functioning correctly again in regards to uploads through the WP panel.
Is it likely that a plugin could have caused this problem? If so, is there a way to determine which plugin it was? I don’t usually let so many plugins get out of date, but I was away the month of December so things got away from me.
