Following this thread - are having the same problem with 188.8.131.52
Although not after upgrade, but a fresh magento installation that just wont show images. We imported products from an importfile, where the images are not showing, and we tried to create a new test-product and upload pictures to them with no luck either.
All the folder settings is in order, and the files are in the folder (ftp) after upload in the admin-panel, but just not showing in the backend or the frontend.
At the cms-pages we have the same issue, images are not showing, but are uploaded fine to the media-folder.
Our hosting provider suggested to outcomment the following in the .htaccess file:
Options All -Indexes
But with no luck. PHP Memory limit is at our maximum of 256mb. in the php.ini file. We are running PHP 5.4
