I dont know which plugin you use, but i sounds like a javascript conflict.
So you can do the following:
If you use a SEBLOD custom content template and not the SEB-Template to show your content on the frontend, you can include the code for the social share buttons directly in you custom template.
If you are using the SEB-Template you can do the same with the Joomla template override. Include the social sharing code in article.php of your overrides.
You can find the codes for the social share buttons on the sites of the google, twitter, facebook and so on.
Try it and you will see if there is also an conflict. The conflict could also be caused by javascripts from your template. Its often quite difficult to trace the problem to its source.
