Hello marcelo-guedes,
Thank you so much for using our theme SuperMag. There are thousands of plugin on WP repo and outside the repo. We haven’t tested all the plugin with the theme. We developed the theme on a such way that it will not conflicts with plugin and work well. If you faced the plugin and theme conflicts, we need to check the plugin. So, please provide the plugin file on our email, so that we can check the plugin and try to find the solutions.
Regards
