What were the steps you took to downgrade? You can't just upload the 3.8 files and use the 4.0 database.

[Marco van Herwaarden]

You will need to restore both your files and database to the point prior to the upgrade.

[elenh]

i have upload the vb 3.8.4 files and run finalupgrade.php
I dont have backup to restore database.

[Marco van Herwaarden]

You can not downgrade if you don't have the old database.
