I delete a database from aapanel UI. and go to File to empty recycle bin.
I re-create the same database name, and re-install my php program, for examle, HESK support system.

I got an error message during installation.

Table 'hesk_attachments' already exists

I use phpmyadmin to check the database, there is no structure on this DB, Is there any cache?

    This should be a problem caused by the website installation program, right?
    It is recommended to check whether the configuration of the website program is brand new?
