I am currently developing a website in EE (2.10.3), and everything is working great except one difference between my local version (running on XAMPP) and my staging version on a linux server.
I have written a module that my site makes a call to through ACT id, but this isn't working on the staging site, unless I am currently logged in to the control panel! If I'm not logged in, the request returns a 404 error, with the text "File not found.". If I am logged in, visiting the ACT url will return the correct information.
Just to sanity test that it isn't my module causing the issue, I tried loading a url with some other ACT id, with the same issue. For instance, in my installation, the ACT id for the "Channel" method 'combo_loader' is 4. The url for my local version http://local.example.com/?ACT=4 loads just fine, while the URL for the staging version http://staging.example.com/?ACT=4 returns 'File not found.'! If I log in to the control panel in my staging version, then that url works just fine.
Anyone have any info that can help me debug this?
EDIT: I've narrowed this down a bit. The problem lies in my .htaccess file. Specifically, the section used for Static Cache for the Mustash add-on. If I disable that, things work...
<IfModule mod_rewrite.c>
RewriteEngine on

It's not the last two sections, either. I removed them and the problem persists. The problem only goes away when I remove all that other stuff.
