{if $currentJournal && $currentJournal->getSetting(‘onlineIssn’)}
{assign var=issn value=$currentJournal->getSetting(‘onlineIssn’)}
{elseif $currentJournal && $currentJournal->getSetting(‘printIssn’)}
{assign var=issn value=$currentJournal->getSetting(‘printIssn’)}
{/if}
{if $issn}
{translate|assign:“issnText” key=“journal.issn”}
{assign var=pageFooter value=“$issnText: $issn”}
{/if}

I added the following in …/templates/index/site.tpl after after {if $site->getSetting(‘showDescription’)} …{/if}
But, It does not work.

{if $currentJournal && $currentJournal->getSetting('onlineIssn')}
    {assign var=issn value=$currentJournal->getSetting('onlineIssn')}
{/if}
{if $issn}
    {translate|assign:"issnText" key="journal.issn"}
    {assign var=pageFooter value="$issnText: $issn"}
{/if}
