Could you please share us your Site URL so that we can figure out the issue or check my deactivating the plugins one by one. May be some plugin you are using might have affected the script related to it.
We have checked your Site, The Third Party plugins have affected the core scripts of the Theme so please check your site by deactivating the plugins one by one. We have a doubt that the plugin named “jQuery Updater” might have affected the theme scripts.
