[Michael Trip]

Good evening,

I am trying to configurate some modules with Horde, i log on, i go tho the
layout menu, and then, when i try to add a module, such as IMP (CVS)(Mail) i
get this error

Warning: Cannot use a scalar value as an array in
/backup/www/horde/portal_edit.php on line 412

Warning: Invalid argument supplied for foreach() in
/backup/www/horde/portal_edit.php on line 412

Fatal error: Call to undefined function: setheight() in
/backup/www/horde/portal_edit.php on line 627

but, when i try the latest cvs version of kronolith i don't get this error

what could this be?
