chown -R root:client0 ../testing1.remcycle.net
chmod -R 744 ../testing1.remcycle.net
The site will not work with this chmod settings. Please delete the site in ispconfig, it can not be used for further teststs with this settings.
Regarding your original problem, after you delete the website, create it again. Then try to access it and when you get an error, please look in the apache error.log of the website and post the exact error message that you find there.
Also the document root in your script is wrong, a document root "/var/www/remcycle.net/" can not be used, as /var/www/remcycle.net/ is a symlink to the document root and not the folder that contains the website. The document root is a folder like /var/www/clients/client2/web1
