Anyone can pls guide me how to change the url from  https://site.com to https://www.site.com

i tried adding www in config.php in ow_includes but when loading site it says too many redirects

i also tried doing force redirection via inserting below codes in .htaccess but still same error -- "site is redirected too many times"

RewriteEngine On RewriteCond %{SERVER_PORT} 80 RewriteCond %{REQUEST_URI} !^/[0-9]+\..+\.cpaneldcv$RewriteCond %{REQUEST_URI} !^/\.well-known/acme-challenge/[0-9a-zA-Z_-]+$RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$RewriteRule ^(.*)$ https://site.com/$1 [R,L]

Main problem is Cloudflare is not getting activated without www so need to change url

Thanks

Cheers!
