Error babel/polyfill

Hi there,

I am using the latest wordpress version (5.1) and also the latest X-theme -version 6.4.6.
I am suddenly getting this error when trying to use cornerstone:

cs-vendor.js?ver=3.4.6:35 Uncaught Error: only one instance of babel-polyfill is allowed
at Object. (cs-vendor.js?ver=3.4.6:35)
at Object.1.2 (cs-vendor.js?ver=3.4.6:38)
at c (cs-vendor.js?ver=3.4.6:32)
at e (cs-vendor.js?ver=3.4.6:33)
at cs-vendor.js?ver=3.4.6:34

I tried deactivating all plugins and deactivating the child-theme to the standard x-theme-theme and it didn´t fix the problem. I really can´t use my Cornerstone editor at all for the moment. Please help.
thank you

Hello Sören,

Thanks for asking. :slight_smile:

As you have tried the solutions and to test the issue further, would you mind sharing the login details in secure note for us to take a closer look?

It is very common to need to share sensitive information with our staff such as login or FTP information. In order to keep this private, be sure to use the Secure Note button that you will find at the bottom of each reply.

Thanks.
