RE: Ngrok functionality & Wordpress
Funnily enough, I have just copied some updated plugins from my Local WP-Content into the Laragon WP-Content of another site I am working on and - voilaaa this one stopped showing WP-Admin bar also. But when I migrated them from Local two days ago both worked without problem.
On Local I was using nginx which I enabled also on Laragon and as I said they both worked after migration. That is the only think that does not make sense now.
