I am trying to:


I am developing a new website for the company, on a test server with no DNS entry, and I have updated WPML to 4.0.2 and also 4.0.3 and the browser redirection is blocking the website in IE 11. It works in FF and Chrome.

It seems that there is an error in


You can see it in the console.

SCRIPT5009: 'Symbol' is undefined
File: app.js, Line: 8, Column: 14526

Practically, the website stops loading at this point and it doesn't work properly since some other files should be loaded afterwards.

If I deactivate the browser redirection, everything works just fine.

I still have the WPML 3.9.3 on the live website and it works just fine. It seems that you have changed the browser redirection script afterwards.

I hope you can check.

Thank you.
