Hello,
I am an Expert Wordpress Developer with 2+ years of experience in Wordpress. I have worked with all kinds of Wordpress Projects including Theme/Plugin Development, Blog setup and customization, Theme/Plugin Customization, Speed Optimization, Security Improvements.
I think this is due to some confliction in javascript. Let's discuss more on chat and I will let you know exactly how much time it will take. I will try to resolve this asap so that none of your customers have to face this for long.
Looking forward to working with you. Feel free to contact if you have any questions/query.
Thanks
