Stripe API stops working when redirecting from a different folder – Apache

Not sure what’s going on, but when I downloaded a stripe checkout application into my computer and ran it through my terminal, it works. The logs on my stripe dashboard gets multiple events without errors.

php -S localhost:4242

I installed stripe CLI to test out webhooks, but then encountered this problem. Either way, it helped me debug a little.

stripe listen --forward-to=localhost:4242

Stripe logs when I go to localhost:4242/index.html and click on the button that’s supposed to start the "subscription" process:

Here’s where the problem starts. I created a website with a login system and bunch of stuff, and my intention was to link this stripe checkout application to that login system, so I needed access to $_SESSION variables. Here’s my folder structure by the way:

Root
|── /includes
│   │── login.inc.php
│   └── logout.inc.php
│
|── /stripe_test
|    │── index.html
|    │── createcheckout.php
|    │── config.ini
|    │── config.php
│    └── script.js
│
|── /loginpage.php
|── /editprofile.php
|── /logoutpage.php
|── /index.php
|── /header.php
|── /footer.php
└── .htaccess

I added a simple link in root/index.php that redirects to root/stripe_test/index.html, making it kind of a "pick a plan" page. I should mention that I’m hosting the root directory in xampp, localhost:8080, which is even weirder. Cause opening that stripe html page from localhost:4242 makes it work as intended. In a nutshell:

• localhost:8080/stripe_test/index.html – doesn’t work (via xampp)
• localhost:4242/index.html – works (via terminal: php -S localhost:4242)

I checked my apache error logs and here’s what it shows after clicking on the button:

I have no idea why the directory has two "backslashes", but it probably has something to do with the .htaccess file and the in my header. Here’s the htaccess directives:

Options -MultiViews
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ - [L]
RewriteRule ^profile/([w-]+)/?$ profile.php?userid=$1 [L,QSA,NC]
RewriteRule ^([w-]+)/([w-]+)/?$ city_page.php?state=$1&city=$2 [L,QSA]

Can someone explain what’s going on here? I reckon the main issue is the htaccess and the base href, since it works when I target the actual folder stripe_test in my terminal and run a server directly from that directory. When I run a server using my xampp, which then uses those .htaccess directives and that base href, that’s when the error.log shows weird paths.
