If your site has been hacked, I would recommend downloading WordPress file and replacing all core files.
That’s why I said, delete wp-includes folders completely and replace with new. Same for others core files. (Don’t delete wp-config.php, .htaccess, robots.txt)
Is there any chance to lost my website if I do so?
Good question, Rajdeep.
Yes, there is a huge chance if your site uses outdated theme and plugin that doesn’t work properly on latest version WordPress. I would strongly advise please take server level backup before proceeding.
I keep everything updated, may i get your whatsapp number or calling number sir ?
If everthing is updated, then there shouldn’t be any problem. However, keeping backup first is recommended.
files replacement done.
evrything working but site is slow down 1 to 2 sec
If your site is loading slow, allow sometime to build cache and check after sometime.
