[RESOLVED][Apache/PHP5] Accessing controllers throws an 404 error

First off I would check the php version running on the server.

Check the php installation and that all the right modules are compiled into it.

Check the Apache installation also.

Hey.

The php version running is 5.4.45. (Yes, I know, rather ancient, but I already tell everyone that we should prioritize migrating to PHP 7 ASAP.)

As for the modules, I can't really say which are included vanilla and which would be known to cause the issue.

I've tried using PHP 5.4.45 on my local machine just now and CodeIgniter worked as intended with it.

If you can hint me to where to look for the information needed to figure out the issue, I'll gladly post those. Or maybe you might have an idea which module or config property could be the perpetrator?

Edit: I found the problem! I actually found a different .htaccess snippet from InsiteFX here on the forums and that did the trick. I think it had to do with how Apache integrates PHP. Thanks though!
