​
Database Issues

In MainWP Dashboard 6.2 or later, open MainWP > Info > Server (admin.php?page=ServerInformation) and scroll to Database. This section checks MainWP tables on your Dashboard site, including supported Add-on tables, and reports missing tables, missing columns, incorrect column definitions, and missing database privileges. Database health results in dark mode showing MainWP table details and green check marks A green check mark means the checks performed for that row passed. For a red cross, read the accompanying message:
  • Missing database privileges: Ask your host to check the database user’s permissions and provide the listed missing privileges.
  • Missing tables or column issues: Send the exact table and column details, along with a system report, to MainWP Support.
Clear Search system report before downloading a report so all rows are included. The check reports issues without repairing tables or restoring data. Reload the page after an issue has been addressed to check again. See MainWP Database Health Check for result explanations and instructions for sharing a report.

Contact Your Host

For most changes, contacting your hosting support is the safest approach. Provide them with:
