Bizarre Issue with mod_rewrite or something else

[HDFilmMaker2112]

I'm having a bizarre issue with Mod_Rewrite.

 

When I type mydomain.com/signup into my browser it's going to signup.php not index.php?signup as expected.

 

It seems my server is first looking for a file that has file name of signup. I noticed this earlier too because I have a file called signup.css, and it was loading that when I went to /signup; but didn't think much of it at the time.

 

RewriteEngine on
RewriteBase /

RewriteRule ^signup$ index.php?signup
RewriteRule ^signup/(?:$|\?(?:.+)) index.php?signup$1 [QSA]
RewriteRule ^activation/(?:$|\?(?:.+)) activate.php?$1 [QSA]

AddType x-mapp-php6 .php 

 

Any ideas on what's happening here?

I unfortunately only want to rewrite specific URLs so something that's does everything won't work. Which I'm not mistaken that does?
