Reescritura de página personalizada

[Starfish Host]

We have recently worked on adding new custom pages to whmcs under the standard and criteria of the documentation.

We are needing to remove .php from some urls.
By doing some research we have found viable methods, but we faced some problems.

The simplest and most common method is to remove the extension of specific urls, this really seems very nice because it avoids possible complications with the flow of whmcs.

RewriteRule ^ company $ company.php [QSA, L]

The slightly more advanced and functional option is:

RewriteRule ^ (fileName1 | fileName2) /? $ /$1.php [L, NC]

But this method I need to comment on some lines of the default generated by whmcs and later, the login stops working. I assume probably other urls alike.

I need to achieve a mix between the rules to make the custom pages work without .php.

Any contribution you can make to me?
