Hi All, We need to migrate our existing application with custom modules (KOHA Version 16.05.04) to latest version (KOHA Version 18.11.05). Existing application deployed in cloud server. So we have done the following steps. - Installed the KOHA Version 18.11.05 in another cloud server. - Migrated the old database to new server. - The corresponding custom code snippet copy from old server files and paste to new server files. - But in the case of .pm files, copy the entire files from /usr/share/koha/lib/C4 and paste to the same location in the new server. Now when we click on one custom link, we got the following software error. *Software error:Bareword "GetItemTypes" not allowed while "strict subs" in use at /usr/share/koha/opac/cgi-bin/opac/libraries.pl <http://libraries.pl> line 185.Execution of /usr/share/koha/opac/cgi-bin/opac/libraries.pl <http://libraries.pl> aborted due to compilation errors.* Can anyone help me urgently on this issue?
