I’ll just paste a question I’ve asked to the dev of one of my plugins and his answer, as this is the easiest way to explain the situation:
Another issue I’ve just detected: when I display those social buttons at Auction Pro pages, the tabs, like description, shipping, etc., stop working for non logged in users and also for super-admin (you can use them normally when logged in with that test account I’ve sent you the credentials for though). You can reproduce this issue by marking the “Page” box at that social buttons plugin settings, here: https://www.wheelofcommerce.com/wp-admin/options-general.php?page=mr_social_sharing
Response – I noticed that different tabs in dedicated auction page were not clickable and found that there is a plugin installed called Social Sharing Toolkit which is giving JS errors inside console. When this plugin is deactivated then shipping and tabs work fine. Hence this plugin is the culprit. I also noticed via JS errors that you might have shifted your site from http to https and all links on your site were not shifted from http to https and that is why Social Sharing Toolkit plugin is throwing JS errors. I would recommend you to solve those JS errors and then use Social Sharing Toolkit plugin or else use all together different plugin for social sharing.
How do I fix this?
