Fri, 10 Apr 2026 18:48:32 +0000 https://bugs.horde.org/ticket/12237 ActiveSync and TopBar cause logging errors I get lots of error messages like the below, a bit of digging into the Apache logs shows which requests coincide in time and thus are likely to be the culprits. Let me know what further debugging you may require :) May 5 02:05:14 HORDE: PHP ERROR: Undefined index: class [pid 5950 on line 94 of "/usr/share/php/Horde/Core/Log/Logger.php"] May 5 02:05:14 HORDE: PHP ERROR: Undefined index: file [pid 5950 on line 113 of "/usr/share/php/Horde/Core/Log/Logger.php"] May 5 02:05:14 HORDE: PHP ERROR: Undefined index: line [pid 5950 on line 116 of "/usr/share/php/Horde/Core/Log/Logger.php"] 203.42.219.10 - - [05/May/2013:02:05:14 +0200] "POST /horde4/services/ajax.php/horde/topbarUpdate HTTP/1.1" 200 2012 203.42.219.10 - - [05/May/2013:02:05:14 +0200] "POST /horde4/services/ajax.php/imp/poll HTTP/1.1" 200 88 But I also get the above log entries for the below from AS; 150.101.188.136 - userid [05/May/2013:01:56:07 +0200] "OPTIONS /Microsoft-Server-ActiveSync HTTP/1.1" 200 - 150.101.188.136 - userid [05/May/2013:01:56:07 +0200] "POST /Microsoft-Server-ActiveSync?User=userid&DeviceId=xxx&DeviceType=iPhone&Cmd=Sync HTTP/1.1" 200 73 I also get this for PING requests via AS... Sun, 05 May 2013 00:38:25 +0000 https://bugs.horde.org/ticket/12237#t78009 This was fixed long ago in Horde_Core 2.5.0 (not yet released). It is due to PHP engine limitations (these values are not always available in debug backtraces). Sun, 05 May 2013 02:21:24 +0000 https://bugs.horde.org/ticket/12237#t78010
