Hi. i cvs'up yesterday latest kronolith to work with my horde and imp.
two problems:
when i tried to add a new even i got access denied to table
kronolith_evens_seq
i noticed couple of messages about this table in archives, but sql script
doesnt have it.
only kronolith_events.

today i cvs'up again to see if i might get it and kronolith stopped working
completely, i get  this message:
 Call to undefined function:  singleton() in
/usr/local/www/horde/kronolith/lib/base.php on line 52


any suggestions?
thx
