We couldn't connect to your database.
Make sure that your database is properly configured in config-userfrosting.php, and that you have selected the correct configuration mode ('dev' or 'production'). Also, make sure that your database user has the proper privileges to connect to the database.
One or more tables already exist.
The following tables already exist in the database: uf_user, uf_user_event, uf_group, uf_group_user, uf_authorize_user, uf_authorize_group, uf_user_rememberme. Do you already have another installation of UserFrosting in this database? Please either create a new database (recommended), or change the table prefix in config-userfrosting.php if you cannot create a new database.
