Not sure what I've done wrong but no comments, links or shares show up on the widget - even though the boxes are ticked. Is this a known issue?

Hello Dominic! Thank you for posting about this issue!

Unfortunately I couldn't find the page where the widget is, but the issue is understood. Could you please send us temporary WordPress administrator access to your website? You can forward the information using the contact form on this page: goo.gl/7SbEU1

Also make sure to include the link to this forum thread in your message. Our developers will take a look at the problem as soon as possible and figure out a solution.
Thanks! Have a wonderful day!

Hi Dominic!

Please note, that this issue is occurring because of the too many errors on your website.

Our developers have implemented a workaround and shares/likes are now showing. However, these errors will cause other issues in the future, so we highly recommend you to check them out.

Thank you! Have a nice weekend!
