Hi 

Hello

I had sliders made and working on the site.
the layer slider was linked to the7 template and the template was last updated to version 6.10

yesterday or maybe the day before yesterday the sliders stopped working.
there is something like this in the browser console.

(index): 158 Uncaught ReferenceError: _initLayerSlider is not defined
     at HTMLDocument. <anonymous> ((index): 158)
     at i (jquery.js? ver = 1.12.4-wp: 2)
     at Object.fireWith [as resolveWith] (jquery.js? ver = 1.12.4-wp: 2)
     at Function.ready (jquery.js? ver = 1.12.4-wp: 2)
     at HTMLDocument.J (jquery.js? ver = 1.12.4-wp: 2)

today I bought a license and updated the layer slider. the sliders still don't work!
what should I do?

Ok. the problem was litespeed cache
