Parallels Panel 9.2 is installed on Windows 2008.
Data for web-statistics based on Awstats is not generated for a particular domain. However, other domains do not have this issue.
It is necessary to replace the %plesk_bin%\statistics.exe
file with the attachment
for PP 9.2.1 and 9.2.2 or this attachment
for PP 9.2.3. See the http://kb.sp.parallels.com/en/1802
article about the hotfix installation procedure.
Here is the same fix for the Parallels Panel 8.6 version: http://kb.sp.parallels.com/en/8199
