When setting LevelForFileTypesDetection=0 in the Awstats config file, Awstats starts to count every hit as a page load, ie the number of "Hits" and "Pages" in the Awstats report is identical. In other words, the Pages statistics becomes meaningless. This was not happening with older versions of Awstats, there must have been a change in version 7.0.
While this may not be a bug, it would be good if it's documented somewhere that LevelForFileTypesDetection must be set to 2 even if you turn ShowFileTypesStats off. Currently the documentation only says that leaving LevelForFileTypesDetection=2 reduces Awstats speed by 1%, so users who don't use/need the file types report might be tempted to turn it off.
