Context:
I've literally never used WordPress, until 2 days ago. I was also not part of the original setup of these instances, so I can't attest to the original configuration that happened.
Problem:
There are 2 instances of the website main (prod) and another (meant for testing), both have their own login pages, except when I login via the admin log-in screen on the testing instance, I get redirected to the main instance's admin area, which means I can't update the dev instance's content via the admin portal.
Example:
Prod
www.site.com/wp-login.php --> [redirects to] --> www.site.com/wp-admin/
Dev
webdev.site.com/wp-login.php --> [redirects to] --> www.site.com/wp-admin/
Assumption:
My thinking is there should be something (on the dev instance) that'll allow me to specify where to redirect after successful login?
I've been scouring the net for possible solutions, as well as go through the site's code, but as the folder structure is a bit of a maze, and my context is somewhat limited, any advice that would allow me to narrow down my search areas would be greatly appreciated.
