Wed, 21 Aug 2013 17:18:23 +0000 https://bugs.horde.org/ticket/12593#t80166 I do't know. I was hoping that someone can tell me. I delete only a e-mail in IMP and always get this error message in the horde.log. This issue affects all users. Even if you delete multiple email at once, you get the log entry for each. Thu, 22 Aug 2013 05:41:09 +0000 https://bugs.horde.org/ticket/12593#t80185 There is no way I can see that slicemap['s'] can be anything but an array. Unless someone can debug this, I'm going to close this ticket. Clear your cache as a possible workaround. Mon, 26 Aug 2013 21:34:24 +0000 https://bugs.horde.org/ticket/12593#t80371
