[horde] portal white page

Mon Feb 2 15:32:19 UTC 2026

  If it is a white page, then that means a 500 error (probably), so  
there must be an error message. You can enable full logging in Horde  
and then check the log file to see where it might be erroring. I only  
have "Sunrise/Sunset" and "Mailbox Summary" for my "portal" page and  
it seems to be working.

Administration->Configuration->Horde->Logging (tab)

Log enabled: Yes
conf-log-priority: debug
log-type: file
log-name: /tmp/horde.log   (ensure the apache user can write to the  
location you choose)

Sometimes /tmp isn't allowed for the apache/web user.
