I currently have whmcs installed in a sub-directory so that the base url is http://www.uniquelyyourshosting.com/whmcs/. I also have SSL so the base ssl url is set to https://www.uniquelyyourshosting.com/whmcs/.
In my WHMCS plugin configuration I have the base url set to http, the page slug is clients, and the whmcs slug is portal. I have copied the wp-integration.php file to the root folder of my whmcs installation.
The portal homepage displays properly in the WordPress Page, BUT any link/login... ANYTHING keeps opening in a new tab in the default whmcs location. I am in the process of a complete redesign of my entire site and I really want this integration to work -- it would be SO much easier than trying to convert my WordPress theme to smarty!
I have granted access to my site through the Dev Dashboard that is valid until the 28th. Let me know if you need more time. I truly appreciate any help you can provide. Thank you!
