If you see your slider only if you're logged in as administrator, and it's not visible for other visitors - in most cases this is due to an old Apache/mod_security version. 


How to check if this is the issue:


Please inspect you page with browser's inspector and check for the error below in the Console tab:


Uncaught TypeError: undefined is not a function love-it.js?ver=3.9.2:7


How to resolve the issue:


You can ask your hositng company to update the Apache/mod_security or install this plugin as a workaround until they update it: https://www.dropbox.com/s/vev3oq90nrbb114/vamtam-jquery-cookie-fix.zip?dl=0 .
