I'm intalling civicrm on backdrop cms. Setup returns that installation was succesful. I see the link in the admin bar, but when clicked, the link gives me 404 error.
If I add "?q=", links works, the page display, but any other link doesn't work.
Clean urls works fine on the site.
I'm performing a migration from Drupal 7, were civicrm was updated and functioning.
System: Backdrop 1.18.0 MySQL Database MySQL, MariaDB, or equivalent version 5.5.5-10.3.27-MariaDB-0+deb10u1 php Version: 7.3.19-1~deb10u1 (PHP information) Servidor web Apache/2.4.38 (Debian) Civicrm 5.33.1
I would appreciate any advice.
