You’ll need to read that again and use one of the methods using access to your site files on the server or to the database. Looks like your site is on HostGator, so here’s info on using FTP.

Then I’d suggest this method:

Oops sorry, missed pasting this link:

ohh no…it is written about editing file – function.php of the active theme. but i don’t remember the theme name. i have installed close to 15 themes. now what should i do? shld i edit in function.php in every theme. what will happen if it doesn’t work??

Your site shows this theme:

https://lustyworld.com/Blog/wp-content/themes/portfolio-press/style.css

i got my old blog back but a new problem has occurred whenever i click on post from from home page it show 404 error.
