I am working on creating a new WordPress website for a client. They previously had a WordPress site but then switched to an HTML site in 2013 which is still active on the primary domain. They have two domains, the primary is http://www.yourwipe.com and they are forwarding http://www.mayti.us to the primary domain. Both domains still have WordPress installed on them but are tucked away in folders. I want to build on the mayti.us domain that is being forwarded and was able to update to the current version of WordPress, however I can not access the admin because it is tucked away in the folder and the domain is being forwarded to the HTML site on yourwipe.com. I have not dealt with a situation like this before so I have some questions on the next steps that need to be taken in order to work on the WordPress site and not mess things up. If I discontinue the forwarding will that be enough to give me access to WordPress in order to build the new site? Or do I need to do something else?
Thank you in advance for your help!
