Power CMS stops working when forwarding another domain name
I have an existing site which I'm using Power CMS with and it works perfect. However, I recently pointed another domain name at the same site and when viewing the site from that domain I get the following errors where my CMS content should appear:
Warning: include(/home/dfnback/public_html/cms/WA_CMS/addtosite.php) [function.include]: failed to open stream: Permission denied in /home/dfnmike/public_html/index.php on line 103
Warning: include() [function.include]: Failed opening '/home/dfnback/public_html/cms/WA_CMS/addtosite.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/dfnmike/public_html/index.php on line 103
Fatal error: Call to undefined function wa_getcmscontent() in /home/dfnmike/public_html/index.php on line 104

Any thoughts would be very much appreciated.
