I had installed a new vm with this guide http://www.howtoforge.com/perfect-server-debian-wheezy-nginx-bind-dovecot-ispconfig-3 Exept one thing, i integrated sever in an existing ispconfig. After that, i followed thsi guide http://www.howtoforge.com/forums/showthread.php?p=316585 to integrate hhvm. After all i created a new domain, and installed typo3. Backend runs perfectly under php-fpm and hhvm. But frontend doesnt work. First of all i disabled speaking urls, but i doesnt help. I get blank pages. So i enabled typo3 developement mode in 6.2 and set my ip do devip mask. I checked logs at the following locations: /var/logs/hhvm/ /var/logs/nginx/ /var/www/domain/logs/ All error.files are empty, so how can i find out, whats wrong?
