Our original site had .php added to every url.
We want to have anyone entering the siteurl.com/page.php to be redirected to siteurl.com/page.
The "page" part of "page.php" could be literally hundreds of different names?

Thank you

Steps to test:
Installed Redj and Sh404sef
Created url in sh4o4 called "making-a-transcript-trestle.php"
In Redj created a rule as follows:
From URL: \.php$
To URL: {scheme}://{siteurl}{pathrtrim .php}

I entered mysite.com/making-a-transcript-trestle.php in a browser and it redirected to mysite.com/making-a-transcript-trestle.

It correctly removed the .php suffix

Are these correct steps to prove it works Luigi?

Thank you
