When I try to start bounce processing, the system answers "The imap PHP library is not installed. Please contact your system administrator."
But php5-imap _is_ installed (sudo apt-get install php5-imap) I even removed it (sudo apt-get purge php5-imap) and reinstalled it. And yes, I restarted apache.
I run limesurvey 2.05+ Build 140131.
Does anyone have any idea what could be the problem?
