I just updated theme and plugins. Now the home slider and some essential grid features aren't working. 

Please advise.

yep that's all been done. that did not help.

i also had several problems arise after the latest update.  mostly related to mobile elements not displaying properly.

i tried activating the debug.log to isolate what might be causing it... but BOY, did that become overwhelming 😝

i believe that the error is actually caused by Elementor Pro.  there's some type of conflict with EssentialGrid, and the 'Slides' elementor widget.  I'm not able to debug it at the moment... but i do know that disabling Elementor Pro brings back the missing EssentialGrid sliders after the update.  

Also... the other pages w/ ONLY the EssentialGrid seem 100% fine, but the combination of Elementor Pro widgets (or at least the Slides widget) seems to kill everything on the page.

how do we copy/paste code into ticksy?! 😝 

I don't have the MailChimp <script> snippet in the JS field.  As well, I do not have the MailChimp plugin installed and/or activated.

David, do you happen to have Elementor Pro installed? 

When I deactivate Elementor Pro, the missing items are back in place, but my image slider no longer displays.

When I activate Elementor Pro, the image slider is back, but the Essential Grid items are missing on mobile.  As well, the ImageSlider doesn't slide on mobile devices. (I'd like to note that the ImageSlider *does* properly display on desktop/mobile preview, but not on actual mobile devices.)

I've tried downgrading Elementor, Elementor Pro, Sonaar theme... still no luck.  The ONLY piece that seems to be different is that I duplicated a homepage section. I wanted to create a second ImageSlider on the homepage, that was mobile optimized.

I'm trying to undo whatever it was that I did... but I sure am having a heck of a time identifying the conflict.  I'm not seeing any identifying issues in my browser console... hmm

we don't have that code button available to us :/ 

thank you Alexandre. removing mail chimp JS fixed it. got too many monkeys with their fingers on the wheel!
