Hello,
If the problem is caused by the plugin, you need to contact the support of that plugin.
Please note that we do not give a guarantee for full theme compatibility with all existing 3rd party plugins, and additional customization is outside the scope of our basic support. Also, we do not provide support for 3rd party plugins, because we are XStore theme support team.
