In some configurations the attempt to display media files from "content" Folder fails with an internal server error 500.
The cause of this issue is a functionality in the file uploader that should deny the execution of PHP code in the "content" folder.
On some webhosting providers this doesn't work.
Upload the content of the "patch" folder and replace the existing file.
After doing this, please delete the ".htaccess" file in the "content" folder.
Now it should work as usual.
This patch is compatible with all UliCMS versions since 7.0.0.
Install it only, when this error appears, since this is a potencial security issue.
