I was facing the same issue which was cause of cache and litespeed via htaccess. I have fixed by rename my .htaccess file to .htaccess-disabled and created new .htaccess file and add code from
https://developer.wordpress.org/advanced-administration/server/web-server/httpd/#basic-wp

I used WP Basic code for my website as it is not subdomain:

# BEGIN WordPress

RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

# END WordPress

Choose htaccess code accordingly, Thank you!
