Tip! Image uploads fail, no debugging information shown. Heres how I solved.

I had a problem where images werent uploading. Placing the site into debug did nothing as right after you clicked upload... the window went blank and idled until you got frustrated and closed the browser. Multiple restarts of the server and Apache did nothing.

I was able to solve the problem by stopping apache and removing all the files in the temporary directory (for me it was C:\Windows\TEMP).

Just a heads up I hope that helps someone
