Hello Jose,
Sorry later reply!
I can’t figure your problem, always use a linux server (online vps hosting) to install DF, locally never try to do this installation.
Allways have problems with the installation, and the update never works! Need a fresh installation and then export table from old db to the new db, test if works, then another table and so on.
Isn’t easy to install/upgrade this platform, if you can install, then add your api code and use the api endpoints is good and works. But if exists a bug in the platform and need an upgrade you need to plan a roadmap to make the transition.
About your problem is a table relation problem, I don’t know if is a fresh installation or made and upgrade.
My suggestion, if you can, is delete (drop) all tables and execute the command-line:
php artisan df:setup
and then
php artisan cache:clear
php artisan config:clear
Go to your url and try to access, if all ok, try to add content (from previsous tables or using the dashboard options).
Best regards,
LB
