Available Disk Space Is Critically Low? What WordPress Is Really Measuring
TL;DRAvailable 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.
