The calendar is not displayed.
This is experienced when the users screen name starts with theletter "a".
I poked around a bit and found that this statement was causing the problem:
if { [regexp {/(a|archive)/?([0-9]*)/?([0-9]*)/?([0-9]*)/?} $url ignore ignore2 year month day] } {
I changed that to:
if { [regexp {/(archive)/?([0-9]*)/?([0-9]*)/?([0-9]*)/?} $url ignore ignore2 year month day] } {
It it is working properly now. Can anyone verify this for me? Should this be in bug tracker?
