Webalizer stopped updating stats for sites at the end of the month.

I had to do a system restore last month but after I reinstalled Webalizer it was working up until the end of the month and then for June it stopped work.

Also it says "Generated 15-May-2003 03:32 CDT"

However the stats go up to May 31st.

I am using Webalizer Version 2.01.

How can I fix this?

Some more info:

- Manually starting webalizer doesn't update it

- Rotating the logs doesn't update it

- No errors are reported when I trigger the logs to rotate or webalizer to update

- I tried deleting the files in one of the "stats" folders on one domain and after I ran Webalizer again nothing was updated there
