Please send me the site information (admin account, cPanel information) of your site. I will try to check and give you right solution to fix it. It seem the problem when you import database sample_data.sql.
Please try to edit the file ves_bingo_quickstart/sql/sample_data.sql, then remove all text #__ and create new database and import the sql file.
Go to the site url to setup the theme quickstart again and choose the new database which you just imported sample_data.sql
