I'm trying to install the List Theme in DT Register. I'm following the tutorial given near the bottom of this page: https://www.dthdevelopment.com/support/documentation/dt-register/223-theme-settings . It says to go to "Components > Dt Register > Configurations > Themes > upload the zip package," but when I get to Configuration there's no Themes tab. Anyone have any idea what's going on here? Thanks in advance.
