Missing report

Hi there,

I found all 0 for Hits, files Pages, Visists,etc for some dates under the Daily Statistics

March:
21st
28th

April:
8th
16th
18th
21st

So I checked in the S3 log bucket and there are gz logs in the bucket for those dates. So I guess s3stat didn't proceed those logs. May I know why this happened and also how can those logs be proceeded for inserting back to the report? Thanks.

Clement
