Hi all
i have tried to upgrade the version 4 to 5 with pear
but there is a problem with ajax
in the webmail tle directorues list not run (ever in refresh)
and ins not possible to view the, calendar.

just for test i have backupped the db and i have tried to reinstall with 
the same database,
diring the instllation is going in segmentation fault

i have tried to open and all is run, and the calendar data is present,
  but not is possible to use activesync,
and in the administration interface is not present the link " activesync 
devices"

thes is a log for debug activesync  login?

my linux distribution is debian squeeze
