How to become administrator on new site if already on old one

I am an administrator on the classic site and can upload photos, etc. However, I seem to be unable to do so on the new directory (at least I am not getting an option allowing me to update member photos other than my own). Does my clerk need to do something different to allow me to edit the new directory?

You need to be entered in MLS, using a standardized calling, as a web admin. The classic website used a different method.

Those standard positions entered in MLS that have administrator rights for the new directory are found in the directory helpat the Roles and Responsibilities section.
