[Koha] 404 Error after upgrading to 25.04

Hi, I'm experiencing exactly the same problem as reported by Beda in May 2024: After upgrading to Koha 25.04, several tables in opac do not load (including items, patrons, libraries ... ). The subject thread interrupts after a reported attempt to debug REST_API. Has a solution been found? Any help would be appreciated. Many thanks and best regards, Giuseppe.
