Cause

Webalizer remains as the web statistics engine in a website configuration even after removal. It is a known Plesk bug with ID PPPM-9887, which is planned to be fixed in one of the future product updates.

Resolution

Force configure all domains to use AWStats:

1. Connect to the server via RDP.

2. Run PowerShell as Administrator and execute the following query:

   PS plesk db -Ne"select name from domains where htype='vrt_hst'" | % { if ($_) { plesk bin site -u $_ -webstat awstats } }

3. Wait for the daily job to execute again or use the instructions from one of the following articles:
