So this is the annoying kind of problem where something works perfectly on your local project, but everything breaks once deployed in production.
In this case, i can access all the pages generated by a regular codeigniter controller (situated in application/controllers). However, once i try accessing a HMVC module, i just get a codeigniter 404 error.
Situation still ok for regular controllers:
So for instance, if i have a regular controller C1 situated in application/controllers/C1.php, which contains the function page(), i can access www.mysite.com/C1/page without an issue.
Problem for accessing HMVC controllers:
However, if i want to access the controller C2 situated in application/modules/C2/controllers/C2.php, through the url www.mysite.com/C2/page, i'll get a 404 error.
And problem accessing regular controller through ajax:
A second issue appears when performing an ajax call, using a path which references a regular CI controller. The path used in the ajax call doesn't seem to be recognized, and i receive a 500 error. However, when calling the same path directly in the URL bar, the correct function seems to be executed. I had solved a similar issue before by applying the solution found in Codeigniter base_url() not working properly for ajax. However, i have not yet identified if this is the same issue.
It feels like a loader issue, but i'm no expert!
Even if it was a loader issue, why would it work on local and not on production?
Have you ever encountered something like this? Do you have an idea on how to tackle this issue?
**Edit 3: ** I removed the 2 previous edits because they are now irrelevant.
After activating the debug mode, and adding some logs, i finally found what i think to be the answer.
Long story short, my local codeigniter version runs on windows, and for some reason, when trying to reach a controller, the case is ignored. So File.php and file.php are considered the same.
My production server however runs linux, so it doesn't consider that 2 different file names refer to the same file. So i ask for file.php, and the server answer "there's no such file", because the file i actually want is File.php.
I need to turn in. I'll propose a proper answer tomorrow after running some more checks.
