Plesk

Fix common Plesk problems yourself with Repair Kit

Use the Plesk Repair Kit extension to restart services, fix file permissions, repair databases and check DNS, and learn the admin plesk repair command for deeper fixes.

BeginnerPlesk2 min read

Many website problems on Plesk have standard fixes: wrong file permissions after an upload, a crashed database table, a stuck service. The free Repair Kit extension gives customers safe buttons for these fixes, and administrators have the more powerful plesk repair utility.

Before you start

  • Administrators: install Repair Kit from Extensions → Extensions Catalog and make it available to customers.
  • A recent backup before running repairs on important sites.

Customers: open Repair Kit

Go to Websites & Domains, open the domain and click Repair Kit (it may be under the domain's More menu or the dashboard). The page lists checks and fixes for your subscription.

Typical fixes

ProblemRepair Kit action
403 errors or "permission denied" after uploading filesFix file permissions for the website
"Table is marked as crashed" database errorsCheck and repair databases
Site down after a change, PHP-FPM stuckRestart the site's web services (where allowed)
Website not resolvingCheck DNS to see if the domain points to the server

Each action explains what it changes before you confirm. Run one fix at a time and test the site after each.

Administrators: plesk repair

Over SSH as root, the plesk repair utility checks and fixes much more:

  • plesk repair all -n – check everything and report problems without changing anything.
  • plesk repair fs example.com – fix ownership and permissions of one domain's files.
  • plesk repair web example.com – regenerate web server configuration for a domain.
  • plesk repair db – check and repair Plesk's own database.
  • plesk repair mail – fix mail server configuration and mailbox permissions.

Always run with -n first to see what would change, then run without it to apply fixes.

When repairs do not help

  • Read the error in the Log Browser – application errors (a plugin bug) are not fixed by permission repairs.
  • Follow the site not loading checklist.
  • Restore from backup if files were damaged or infected.
  • Contact support with what you tried and the error message; MdmHost customers can open a ticket.

Troubleshooting

  • Repair Kit not visible: not installed or not enabled for customers.
  • Permissions break again: a deployment script or FTP client sets wrong permissions; fix the tool's settings.
  • Database repair fails: severe corruption; restore the database from backup.
