MagePlaza OneStepCheckout: The `/onestepcheckout/` frontend page does not work: «Cannot read property 'is_region_required' of undefined»

You should provide me a working website before my work.

Dmitry,

I do not see this error either, please see:

Use my customer account to reproduce the error:
email: admin@mage2.pro
password: deyup2us3ugE

Okay but regardless of this the module doesn’t show up when I’m not logged in, checking out as a guest with no console errors?

Yet again: You should provide me a working website before my work.
Fix this error first.

Hi Dmitry

I’m not sure why you’re so rude - we’ve bought your plugin and we’re asking politely for assistance?

There is no error when I try to check out as a guest, and the module still doesn’t show…

You only see that error when you are logged in which we will fix separately

OK, I will ensure my extension is working only for the guest case.
Do not disturb be later for free regarding the registered case.
Any repeated reinstallation will be paid, not free.
