With version 3.7.10 on joomla 3.9.26 I have not any problems, but after upgrade, I have created a new page, after saving its ID was equal 0. I can not edit it in backend, I see and edit it in frontend, but I can not save the change. Furthermore I can not create any page or save change of the exitent ones. In the past, i have had the same problem, but I solved change the ID manually directly in DB. But with the current version the database structure is changed and I do not known where the ID is stored. Can you help me? Thank you. Maurizio Romani
