Wordpress Blog & Opencart Shop SSL Problem

Hello! I am in need of help with my website for my clothing brand. I have a Wordpress domain [login to view URL] and then an Open Cart subdomain which is shop.sifnation.com. I am having issues having my SSL certificate working properly with my subdomain so that I can have a secure checkout in my online store. I purchased a wildcard SSL certificate from GoDaddy and had it installed on my server with BlueHost. I selected in the admin section of my Opencart to use SSL but I hadn't changed anything in either of my config files. When I would type in [login to view URL] the landing page would not be my Open Cart store but rather the Wordpress page (that would be from [login to view URL]) After talking with tech support from Bluehost, they added to my htaccess file: #.htaccess WildCard SSL RewriteEngine On RewriteCond %{HTTP_HOST} ^[login to view URL]$ RewriteCond %{REQUEST_URI} !^/shop/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /shop/$1 RewriteCond %{HTTP_HOST} ^[login to view URL]$ RewriteRule ^(/)?$ shop/[login to view URL] [L] Now when I go to [login to view URL] it takes me to Open Cart but the landing page completely loses the template until I click something else (See the first screenshot) When I go to my [login to view URL] files and change the HTTPS server to the following: (In my shop folder) <?php // HTTP define('HTTP_SERVER', '[login to view URL]'); define('HTTP_IMAGE', '[login to view URL]'); define('HTTP_ADMIN', '[login to view URL]'); // HTTPS define('HTTPS_SERVER', '[login to view URL]'); define('HTTPS_IMAGE', '[login to view URL]'); (and in my admin folder) <?php // HTTP define('HTTP_SERVER', '[login to view URL]'); define('HTTP_CATALOG', '[login to view URL]'); define('HTTP_IMAGE', '[login to view URL]'); // HTTPS define('HTTPS_SERVER', '[login to view URL]'); define('HTTPS_CATALOG', '[login to view URL]'); define('HTTPS_IMAGE', '[login to view URL]'); Everything seems to just mess up- turning [login to view URL] into a disaster seen in the second screenshot and taking me to an INCORRECT admin login when I go to [login to view URL] seen in the third screenshot. Really would like this fixed ASAP and to understand why this is happening.
