Symptoms
- The server has less than 100 domains.
- The Domains list takes more than 20 seconds to load when all domains are listed.
- UptimeRobot extension is installed and active.
- Disabling the extension reduces the loading time.
Cause
This time increase is expected as the UptimeRobot extension may have the need to check/scan the domains while they are being listed by Plesk.
Resolution
Shorten the list to, for example, 10 domains per page to increase the loading time.
