Configuration error

Hello all,

I have a wordpress website, hosted on hostinger. Yesterday I updated Google site kit and Litespeed cache plugins but after updating I can’t log in to my wordpress dashboard. After many enquiry, I found out that in my wp-config. php file there’s are ‘null’ words 1500 times. I simply download this and edited that. After that when I try to login to my dashboard of wordpress, there’s an error. The error is like:

Configuration Error: Your wp-config. php file has an empty database table prefix, which is not supported.

I even checked that my database’ username, hostname all are correct in wp-config. php file. I previously used Wps- hide login plugin but now I even disabled it by my hpanel’s file manager.

please help me what can I do to login to my dashboard. Unfortunately I forget to do a backup of my site on hpanel. Suggest me some help.
