THAT'S IT i looked into the error log and found, that suexec stops execution if the file is writeable by others than the owner!!!!
chmod to 777 is TO MUCH RIGHTS! All can write the script an suexec generates a error 500!!!
chmod 755 is exactly what suexec needs an the script runs!!!
maybe we should add a cronjob which runs every 30 minutes and changes the rights, because if a user uploads a script and didn't know this he sets the wrong parameter and a 500 error is generated (and the user thinks the provider makes something wrong).
