Suave and Learnpress

I’m creating some courses I want to sell on my website. My theme is Suave (but support has expired, so they don’t help anymore) and the plugin for the courses is Learnpress. The problme is that I don’t have any page where peole can create their own student account. I don’t know if I have to install a specific plugin and, in case, which one is compatible with the website, or if there is something I can fix in any way. The plugin support says I have to ask the theme support, but they don’t answer anymore, as I told.

Thanks a lot
