I recently upgraded to 4.1.2 and all of a sudden I cannot edit anything, anywhere in the dashboard. I also cannot create any new posts, categories, users, anything that requires an update. I thought maybe it was because of the automated upgrade link in Fantastico, so I deleted everything (all files and database) and started from a fresh install. No change. I am using IE9 and an ApacheX server platform. I have not tested another browser. I know it must be a simple fix but until you find the solution, it might as well be rocket science! Any help would be appreciated!
