ReferenceError: N2R is not defined

Hi @a223123131,
This error usually happens if your site has a plugin which tries to reorder inline JavaScript codes. The solution depends on the plugin which cause this error. I suggest you to try to make the plugin inactive which probably do this optimization and if the error gone, the best if you tell us which plugin was the cause.

In the past days, I have seen this error with WP Rocket, when the option “Load JavaScript deferred” was enabled. We have an unreleased fix for this, so let me know if it is the cause and I will attach you an installer which should solve this.

Thanks for getting back so quick.
You are right, deactivating WP Rocket and the error is gone… but the option “Load JavaScript deferred” WASN’T enabled, so it must be something else within WP Rocket

Here you can download the free installer which contains the fix. Could you give it a try to see if it helps?
