Also, we usually recommend VPS or a dedicated server for wplms. Wplms is not just a simple theme like others which are just used to display pages.Wplms has so many features and settings related to LMS. IT also uses buddypress (social plugin ) and woo commerce (used for products and payments ) which are in itself a bit heavy for shared hosting.
The hosting service we recommend is Wpengine.
