Logrotate

I am running VM GPL since a long time. At some stage I had to remove the website, awstats and logrotate from 2 domains. Now I wanted to re-enable the websites in VM's enabled features for these servers.

Apache and Awstats was created without problems, but logrotate fails with

Log file rotation failed! : .. the log file /var/log/virtualmin/xxx.org_access_log is already being rotated at ../web-lib-funcs.pl line 1397

Any one an idea what that could be?
