I added an AdminSettings.php file to the wiki root. Then I ran "initStats.php" from the maintenance directory, from the shell. Here is my output, but the numbers are not reset back to 0.
Is that what initStats.php is meant to do? I would have thought it was meant to set the stats to the correct values after they have become incorrect for some reason. The stats saying there are 0 articles when that's not true would be very confusing... it could result in negative numbers if a pre-existing article were deleted. If you want to set the stats to 0, I guess you would have to modify the database directly, but the code will probably set them back to the correct values once it realises they are wrong.
