The chiangmaicleaning.com is the actual company site which is a joomla install. I installed wordpress as a subdomain in order to make a employee rewards system. When i create a subdomain for the top level domain it makes a folder in the chiangmaicleaning.com folder named “staff”. I have only made one install and i have not altered the .htaccess file in anyway.
I have just checked the general settings and under WordPress Address (URL)
Site Address (URL) it has https://www.chiangmaicleaning.com/staff when i change this to reflect staff.chiangmaicleaning.com i can no longer login and it breaks the site
