On maya-erp.com, your plan sets the number of pages per website: the plan that includes a one-page website with chat refuses to add a second one, and invites you to upgrade.
The limit is counted site by site, and it applies when you add, duplicate or import a page.
Creating a site from a template only keeps the pages your plan allows.
Changing plan never deletes a page already published.
