Convert the links in the template from .php to .html

[RealArkosoft]

Hi, i would like to convert with a rule all the links of the template which are .php to .html

I tried to insert this rule in the .HTACCESS file:

Quote

RewriteCond% {THE_REQUEST} (. *) \. Php
RewriteRule ^ (. *) \. Php $ $ 1.html [R = 301, L]
RewriteCond% {THE_REQUEST} (. *) \. Html
RewriteRule ^ (. *) \. Html $ $ 1.php [L]

and it actually works, it converts all pages from .php to .html including GET variables.

The problem is that other things don't work: how to check if a domain exists, or not to enter the WHMCS panel and more.

Is there a way to convert only the template pages to .html and leave the other pages as they are so they can use the WHMCS panel or cart and more?

Thank you
