Fri, 10 Apr 2026 19:28:37 +0000 https://bugs.horde.org/ticket/9821 Invalid argument supplied for foreach() Just found this error some times in horde's log - don't know exactly which action it takes to reproduce. It occurred when I set some mails as read, but this action applyed correctly. 2011-04-06T11:13:41+02:00 WARN: HORDE [imp] PHP ERROR: Invalid argument supplied for foreach() [pid 19465 on line 169 of "/var/www/horde4/imp/lib/Mime/Viewer/Html.php"] When this error is logged, an server-error-notification is popping up in frontend. Wed, 06 Apr 2011 09:46:28 +0000 https://bugs.horde.org/ticket/9821#t63213 Just added Horde::debug($related_part->getMetadata('related_cids')); an line before foreach is called. It's reproducable for messages triggered by an alarming kronolith event with email-notification. When viewing the notification-mail the first time in dimp (not cached), the error is logged. 2011-04-07T15:59:54+02:00 DEBUG: Variable information: NULL Backtrace: 1.

See attachment Fri, 08 Apr 2011 08:35:56 +0000 https://bugs.horde.org/ticket/9821#t63309 Something strange is going on. I see that message fine, without errors.

Does the 'related' entry in imp/config/mime_drivers.php have 'inline' set to true? Fri, 08 Apr 2011 18:26:40 +0000 https://bugs.horde.org/ticket/9821#t63347 Related has set inline=true, yes. Mon, 11 Apr 2011 12:13:32 +0000 https://bugs.horde.org/ticket/9821#t63465 To further debug this issue, we need details of the IMP -> IMAP/POP communication. To enable debugging, see instructions contained in imp/config/backends.php (the 'debug' config parameter). Debugging should not be enabled on a production server, Attach/post only the portion of the log that directly deals with the problem reported (it may be simplest to clear the log file and then perform the event that causes the error).
