When trying to upload an image .jpg file to my library, I'm taken away from my Dashboard and directly to my blog's Home page with a message stating "Not Found. Apologies, but the page you requested could not be found. Perhaps searching will help."
I wonder if anyone else experienced this problem and whether there's something I should do first to avoid the issue?
I regularly adopt the new versions suggested, but I haven't tried to upload new media images for a very long time, probably a couple years. This trouble may be unrelated to the new version if it started before but I was not aware. The last Theme I uploaded, which is the one I currently use is Twenty-Ten, version 1.4. I was able to change the image successfully and I'm not trying to change that image. I just need to add a new one for a blog I'm working on.
Would someone like to help?
