I have noticed that the footer doesn’t load in the article page. The footer loads in all the pages, except in the article page. Previously I have installed OJS 3.1 journal and that doesn’t have this issue, Someone know how to resolve this problem?
Thanks a lot for your response. You are right. I have found that the Plum Analytics Plugin calls to undefined method PublishedArticle::getPubId() that was failed for some reason. I have disabled this plugin and my article page now is loading the footer.
