After either upgrading to or directly installing Koha ver. 18.xx anytime I try to install a language pack, I get the following error: Connection to the memcached servers '_MEMCACHED_SERVERS_' failed. Are the unix socket permissions set properly? Is the host reachable? If you ignore this warning, you will face performance issues. Use of uninitialized value $pref_name in concatenation (.) or string at /usr/share/koha/misc/translator/LangInstaller.pm line 197. Use of uninitialized value $pref_name in concatenation (.) or string at /usr/share/koha/misc/translator/LangInstaller.pm line 239. On my /etc/apache2/sites-enabled/koha.conf I have set the following lines to opac and intranet, and on the about page it says memcached is running SetEnv MEMCACHED_SERVERS "127.0.0.1:11211" SetEnv MEMCACHED_NAMESPACE "koha" SetEnv MEMCACHED_SERVERS "127.0.0.1:11211" SetEnv MEMCACHED_NAMESPACE "koha-yonetim" I also can not use most of management module and opac module after the upgrade, like borrowing. Below is one such issue. Template process failed: undef error - DBIx::Class::Storage::DBI::_dbh_execute(): Table 'koha_koha.club_enrollments' doesn't exist at /usr/share/koha/lib/Koha/Objects.pm line 269 I had none of these issues in the previous versions.
