I know that there is several threads on this topic, but I cannot seem to find a solution that works for my site.
On image upload (using flash uploader) I get the "http error" and when I use the html uploader, I get an internal server error. With the image upload, if you refresh the browser, the image appears to have uploaded anyway, but thumbnails are not generated. If you select the image to edit, the image contains no data and the system asks to reupload.
This happens with the 2011, 2012 themes as well as installed themes. I've ruled out plugins as I've disabled everything and still the error persists.
I have tried increasing the PHP memory limit (128MB), various .htaccess alterations and I have contacted my host server (who will not deal with "third party" programs...ie.Wordpress).
I'm not sure what other options to try at the moment. Does anyone have any suggestions to what has worked for them?
I'm running WP 3.5.1
PHP Version: 5.3.20
MySQL Version: 5.1.68-cll
Web Server Info: Apache
PHP Memory Limit: 128M
PHP Post Max Size: 64M
