At least some RewriteRule patterns are not matching

[hughbris]

I've been trying to convert a site I inherited's URLs to lose their .php extension using your image. Two variations of rules I have tried result in 404s in the container, but work on the shared production host and on an online htaccess tester. The rules are:

RewriteRule ^([0-9a-z-]+)$ $1.php [NC]

and

RewriteRule ^([^\ \.]+)$ $1.php [NC]

(I know, they are not quite the same matches, but either will get the job done in this case :) )

Another rewrite rule to change legacy index files does work: RewriteRule ^index.(html|php)$ / [R=301]

Docker is my local dev environment. The annoyance with this not working is that my menu links won't work locally.

Also, I tried setting a RewriteLog directive to diagnose the problem, which resulted in a 500 error with Apache's error log saying: "Invalid command 'RewriteLog', perhaps misspelled or defined by a module not included in the server configuration".

Do you have any idea why these patterns might be failing in your image's containers?

Edit: for example, /about-us should rewrite /about-us.php. Even when I test ^about-us$, it doesn't match.
