I have customized a bootstrap theme a little and In article_summary.tpl, I have added the following line to get the PDF count on TOC (if this has to do anytihng with this error):

{foreach from=$galleys item=galley name=galleyList}
{$galley->getGalleyLabel()}: {$galley->getViews()} &nbsp
{/foreach}

Looking forward for your help

Hi @seisense,

Yes, I think the issue is related to the modification. On the site-wide search, search results are presented outside of any particular journal, but the deprecated getViews function assumes that the user is browsing the site within a single journal.

The quickest thing is probably to check if {$currentJournal} exists in the template before calling {$galley->getViews()}.
