I had downloaded the script yesterday morning from the Contribs site.
After I had botched the syslog facility entry by setting it to the email option (which resulted in an inability to log into Horde at all!) I restored to previous configuration by overwriting the conf.php file with the conf.php.bak file. This worked.
Interestingly, this morning when I went back into Horde to enter the LOG_SYSLOG value that you had provided, it was already there. I'm not sure then how it vanished the first time.
The only other glitches I've found:
1) it always shows the last login as "Never." Previous version of IMP displayed this correctly.
2) Kronolith doesn't seem to indicate which calendar you're currently looking at when you choose one from the drop down menu "My Calendars".
Anyone know of a good place to get docs on these applications? horde.org is kinda thin, and there are a lot of settings and tweaks for a newbie
Thanks!
