please check this again
https://grocerystorecoupon.org/2/

I was using extract.php file to get file contents

RewriteEngine On
RewriteRule    ^([0-9]+)/(.+)  extract.php?l=$2 [NC]
RewriteRule    ^([0-9]+)/$ extract.php [NC]
RewriteRule    ^([0-9]+) extract.php [NC]

and that is why
https://grocerystorecoupon.org/2/about was redirecting to
https://grocerystorecoupon.org/about

I dont want to redirect…
Link must be https://grocerystorecoupon.org/2/about

now I have set the .htaccess to

RewriteEngine On
RewriteRule    ^([0-9]+)/(.+)  $2 [NC]
RewriteRule    ^([0-9]+)/$ index.php [NC]
RewriteRule    ^([0-9]+) index.php [NC]

and again it is showing page not found

oh sorry about that ??
/2/
/3/
/any_number/
these all should show the content of https://grocerystorecoupon.org/
but the link must be https://grocerystorecoupon.org/2/

same goes for https://grocerystorecoupon.org/2/about
https://grocerystorecoupon.org/999/about

they should show content of https://grocerystorecoupon.org/about/
I hope I am clear
