Thanks for replying!
We have been checking the site and you are right about the problem.
Does it still happen if you export and install a fresh (unmodified) Beauty Salon theme?
It seems that some javascript code is missing in your frontend (javascript code comments for mobile icon), are you using any Minify/Cache plugin? Can you try to deactivate it to see if the problem is there?
If nothing helps: please, can you send us your theme .TXT exported file to hello (at) themesgenerator.com? so we can try to replicate the problem.
Thanks!
