Hello There,
I have logged in and edited the page. It seems that there is a JS error. Upon checking I noticed that you are using CloudFlare. Could you purge your site cache and make sure that you are using the recommended CloudFlare settings? You can find out about it from this link: https://xthemetips.com/using-cloudflare-rocket-loader-with-x-pro-and-x5/928/
Please let us know how it goes.
