I am using odoo v16 community edition. I have created a custom addon of building block which inherit from blog post snippet. The default template of blog post snippet are 1. big picture layout 2. card layout 3. list layout 4. another layout. I just created a 5th custom layout and that worked perfectly. I also activate the odoo auto backup database. the problem is whenever the backup created the 5th layout template not working as expected. the whole design gone and the image not showing. If I deactivate the database backup, everything worked perfectly again.
