Pointing the Virtual Hosts to beta site

[webizen]

from your php trace, your docroot for dev.grunt.com is set up correctly. http://dev.grunt.com did land on /var/www/dev.grunt.com/htdocs/index.php (#14). you need to figure out why zend cache throw that exception.

Regarding the errors seen in admin console, it the same as you see in /usr/local/lsws/logs/error.log.

It seems your vhost configurations were incorrect: $VH_ROOT and $DOC_ROOT should be different for security purpose. error log, access log and user DB should be under $VH_ROOT. Place them under $DOC_ROOT is a good practice. Permission issue regarding "not writable", "not accessible" usually indicates that the folder is not writable or readable by web server running user (e.g. nobody).
