Activation generated database error

Hi,
I just installed the plugin on my website WP 4.3 and when I activated it, it generated the following errors:

r: [Table ‘napapiirixp.wor967_dopbsp_settings’ doesn’t exist]
SELECT unique_key, value FROM wor967_dopbsp_settings

WordPress database error: [Table ‘napapiirixp.wor967_dopbsp_settings’ doesn’t exist]
DESCRIBE wor967_dopbsp_settings

SELECT * FROM wor967_dopbs_reservations

and this message appears on the public page :

Notice: The called constructor method for WP_Widget is deprecated since version 4.3.0! Use
__construct()

Can anyone help with this?
