[kronolith] Problem with Kronolith

[Lutz Mischa Heitmüller]

Hi,

I installed Horde and Kronolith (and Imp, Nag, etc.)
I have following problem:
The only thing it shows me when I try to run kronolith is:


Fatal error: Call to undefined function: iswarning() in
/var/www/syscologne/html/horde/kronolith/lib/Driver/sql.php on line 64


All the other Horde-modules / Progs function without error.
In the Logfile there is nothing about that.


Thank you very much for your help,

LMH
