I am currently running wordpress 3.0.1 on IIS.
I have just changed my permalink settings to use almost-pretty URLs - /index.php/2010/08/example-post. During this change I added a php.ini file to the website's root directory with the required settings:
cgi.fix_pathinfo = 1 cgi.force_redirect = 0
After this change the image uploader no longer generates thumbnails when I upload an image. There is no error message, and the original full size image is successfully uploaded, just the thumbnails are not created. If I remove the php.ini file thumbnail generation works but almost-pretty URLs breaks.
Any ideas how to fix this?
