Thanks a lot for your response. I have revised this topic https://forum.pkp.sfu.ca/t/ojs-3-1-wont-show-remote-galleys/34816/2, and I have realized that my particular situation is that when I created my galley’s some them were created as supplementary galleys, that’s the reason why no render in this new version of OJS 3.1 because in this version those kind of galleys are not visible in the article summary view.
I changed the following templates: templates/frontend/objects/article_details.tpl, templates/frontend/objects/article_summary.tpl and pages/article/ArticleHandler.inc.php
for there is not difference between the primary and supplementary galleys, as the ojs 3.0.2 and 3.0.1.
