I am running 4images under a IIS 6.0 Webserver (W2K3).
When I tried to login or logout the redirect to index.php didn't work (=>Page not found) because there's an error (colon after the port) in the generated url:
http://serverip:9911:/index.phpTo fix it, edit the redirect function in includes/functions.php:
insert the following lines of code above
header($location.$url);
/** remove 3. colon **/
if(substr_count($url,':')>= 3) {
$url = substr_replace($url,"",strrpos($url,":"),1);
}
