You don’t need to make any changes, just update them. * -> Clear cache and reload the pages where you’ve published the tours. * The issue should be resolved after that. * Please let us know if you’re still facing the issue after that. * Regards, * [patryk1990](https://wordpress.org/support/users/patryk1990/) * (@patryk1990) * [3 years, 11 months ago](https://wordpress.org/support/topic/error-the-magic-method-singleton/#post-15766942) * I have same issue and I didn’t expect much, but tried the procedure above. I run on php 8 and since the 8 update most of the magic methods must be declared as public.

It is ok, even one of my page is closed with a password, but it is not the tour that is non public.
