After connecting to the database from my server, the product details and pictures are not displayed............ The UI only sees the register page and other nav bar elements.
Where is the database from - is it an old version upgraded - did it previously have multiple stores configuration ? Or is it a fresh new database in which case - did you enable demo products ?
If not a new database one option is to run the Install and create a fresh new database with the demo products enabled and verify everything is working. If that is all good then you know it is something with the old database
