I am having strange problem after installing multi-site drupal environment on shared host. When executing I am getting front page and page also displays results from database without CSS and JS.
The CSS and image resources are not getting displayed which resides in /sites/all/themes/mysite/. When tried to locate CSS or JS files using URL; it returns 403 forbidden error.
Could you please help me to rectify issue?
This sounds like an apache configuration error. Either consult the apache documentation for your version, or search google (e.g. http://www.cyberciti.biz/faq/apache-403-forbidden-error-and-solution/)
