404 page on Opencart 3.0.2.0

https://bit.ly/3nck5mB - this page for many users does not open (and not only this), and incognito opens. Gives away 404 errors. Not opening KK in Ukraine, and in other countries - complain.

Site on Opencart 3.0.2.0

SeoPro is the most standard, as put (years 2 years ago), and stands - there were no problems.

If the task is familiar - I ask you to add applications and it is desirable to comment on some kind.

Thank you all for your attention!
