Hi Alanya25825,
Have you tried using Sharethis with Sharebar? It works great and you can add share buttons for the major social media networks easily. I have been using the combination for over 5 years on my fitness website. In fact, just recently implemented on my new website which uses a modern theme and it functions great on it as well. You can check out Sharebar using Sharethis buttons on my new site here: https://www.introvertscircle.com/seven-ways-introverts-can-rock-online-dating/ and my old site here: http://www.askthetrainer.com/exercise-information/
Let me know if you need assistance setting it up.
