elementor is not defined

Hi.
We have the same problem at: https://www.baar.ro/info-certificat-de-daunalitate/
The accordeon is not working.
With Inspect in Chrome we get the following errors:

frontend.min.js?ver=1.1.6:408 Uncaught TypeError: Cannot read property ‘querySelector’ of null

It happened when updating the plugins. I tried to deactivate it one by one, but still not working.

I deactivated the Elementor Addons & Templates – Sizzify Lite.

Also, I did rollback to Elementor plugin to a few previous versions. Still not working.

Is there any solution?

Thank you!

I believe I found the reason for the plugin failing.

There is an additional plugin downloadable for Elementor which is called
“Void Contact Form 7 Widget For Elementor Page Builder” by voidCoders which create the error in Elementor. As soon as I disable this plugin everything works as expected.

There was an update for this plugin lately so the reason is probably located there.

Could you confirm this @yuvvraaj and @cipriann?

After I emptied my browser cache I have the total disaster going on and cannot even use the editor at all.

I get this error message.
