can't browse to subdomain on apache server, getting forbidden resource permission

I have cPanelA with website A...with subdomain A1 - all is working correctly. I have created a new cPanelB with website B...and need to move subdomain A1 over to cPanel B as subdomain B1. Website B is working...but after copying all of subdomain A1 over to cPanel B, I can't get subdomain B1 to work. It keeps returning Forbidden - you don't have permission to access this resource In cPanelB, I have verified all the file/directory ownerships are correct. I verified all the file permissions are correct (0644 on files and 0755 on directories). I verified PHP is enabled for the new cPanel (via WHM). After more than an hour of frustration - I then verified subdomain B1 file structure/permissions/ownership were identical to those on subdomain A1. I copied the .htaccess files from website A and subdomain A1 over to website B and subdomain B - and then changed any domain references to the new B sub/domain. So I don't think its my .htaccess files...they actually seem to be working because the root /www/.htaccess file has a rewrite to point to the subdomain folder /www/club and I can see in the browser that its actually making it to the subdomain B. I know this is probably going to be something tedious but I am all out of ideas on what the issue could be. www/.htaccess: Options +FollowSymLinks RewriteEngine On RewriteCond %{HTTP_HOST} ^api\.
