Available disk space is critically low means PHP reported under 20 MB free on the filesystem that holds wp-content. On shared hosting that filesystem belongs to the whole server, not to your plan, so the warning can be wrong in either direction. Read the Disk Usage meter in cPanel instead. Near its limit: clear old backups, logs and unused plugins before updating. Plenty of room: the warning is a measuring problem, not a full site.
WordPress membership site hosting must handle uncached logged-in traffic — something most shared hosts cannot do. In 2026, you need a dedicated IP address, at least 4 PHP workers, Redis object caching, and PHP 8.3+. AHosting WordPress plans include a dedicated IP on every plan, CloudLinux CageFS isolation, and the server stack membership sites actually require.
