I have installed NextGen Gallery for a WordPress blog hosted on my own server: Ubuntu 10.04 LTS, Apache 2.x, MySQL 5.1.63, PHP 5.3.2.
Everything works fine, but when I am trying to upload multiple pictures with the batch uploader, I'm getting the error: "Error. HTTP-Fehler: HHTTP Error".
I have found several other threads dealing with this problem and suggesting to adapt the .htaccess files, but none of those suggestions has solved my problem.
As it is my own server I could try to adapt permissions or other modifications, but I do not know where to start. Is there a tutorial or FAQ dealing with the prerequisites NextGen needs?
Thank you for any hints!
