Problem:
You are trying to translate pages including the WooCommerce shop page, blog page, contact us page, and others, but instead of seeing the translated page, you receive the message: 'Oops, looks like the page is lost. This is not a fault, just an accident that was not intentional.' You are wondering why the pages are not displaying correctly after adding the WPML language switcher and how to fix the issue of the page not being found after translation.
Solution:
According to client the "Event Tickets" plugin was causing the issue and deactivating that plugin the issue is gone
