Many thanks @christopher.amirian
I don't know if when you answer you read the entire conversation in a thread. Before requesting your help I deactivated third-party plugins and deleted the cache a thousand times.
I appreciate your test but I still get the same 2 errors in several computers and browsers.
Cornerstone is not playing the Slider Revolution in its work area, and neither in the browsers.
This has happened to update Cornerstone, the truth is that it's a builder that I didn't like and still giving problems.
Is it possible to install the previous version, the previous step without updating from Cornerstone?
If someone else can and wants to help me, I appreciate it.
