I do get the problem each time I go to the manager, and did not have the error prior to the update. I’ll gladly let you into my admin if you’d want to take a look there. I did deactivate all my plugins and tried with each one reactivated one at a time, but the error occurs even when all plugins are deactivated.
I use chrome as my default browser, for some reason after I moved some images into another folder today, those images gave the image doesn’t show (like a broken image icon) on the spots where the images were placed in the posts. When I opened the site in IE, the images appeared, so I cleared my browser cache in chrome and reopened site and they all the images reappeared just fine.
