Znuny Open Source Ticketsystem

My company is in the process of a merger. We have 2 different domains at the moment and users (customers and agents) on both domains. I've got otrs authenticating from LDAP on both domains, however when I go into customer search, I can only see customers from 1 domain. Any help would be appreciated ...

This is what is in line 588 of AgentFAQ.pm


$Frontend{LanguageOption} = $Self->{LayoutObject}->OptionStrgHashRef(
Data => { $Self->{FAQObject}->LanguageList() },
Name => 'LanguageID',
LanguageTranslation => 0,
Selected => $Self->{UserLanguage},
);

getting this error when trying to access the menu options under FAQ, OTRS 3.0.1

Software error:
