Get simple 3.3.16 support for php 8.0

I18N Search plugin stopped understanding Custom Permalink Structure settings %parents%/%slug%/
In the menu, the links look fine, but in the search they look like this

Code:

http://mydomen.com/%parents%/lorem-ipsum-2/

added to check list.
some errors?

Didn't find any errors in the logs.

how you create custom structure? Default GS?

I only change this, as the I18N plugin allows. The menu gives the correct links for all levels, but the search for some reason does not generate them.
