I am encountering a HTTP error too. When I upload images they simply throw out an error message. I have read through all media related topics and found nothing works to resolve the problem. I have cleared cache and cookies and also restarted my computer, cleared the thrash, updated my version of photographer.
I’m at my wits end :(
Question 2: Is there any way to completely start over in wordpress? delete any and all saved data and reupload the theme etc.?
