Not sure if it is a bug.
In admin.php under the "Site Administration" there is a
pull down list "View log files", I remember that in
previous versions the default file that appears is the
latest one (ie in this case should be pgv-200606.log)
but right now it shows pgv-200602.log for me. I have
to pull down the list and select the current one.
Maybe is my mistake but it might be a bug.
