Opencart Login Without Any User Info

I'm having a serious problem with admin panel. In the admin login page, even if i don't enter username or password I can login to admin panel. I have a website that is using opencart 3.0.3.2. I'm using Journal theme and it's version is 3.0.46.
Any suggestions?
Update:
I followed this: https://blog.sucuri.net/2016/12/unrestricted-backend-login.html and problem is gone.

Integration with paypal redirect issue

I am integrating paypal with my openedx ironwood install.
To implement ecommerce capabilities - openedx ironwood uses django oscar shopping cart.
It works to the point where one can enter their credit card information and submit the form.
However after submitting the form the following error occurs
and this is the corresponding address in the address bar:
https://http/payment/paypal/execute/?paymentId=PAYID-LZWTHVY60U970153W662623L&token=EC-45D081042G524235T&PayerID=UBRT2SFRKASXL
Any idea on how I can fix this?
It appears the URL https://http/payment/paypal/execute/ was given to PayPal as the return URL, and so it tried to return there after payment approval within the PayPal checkout.
You / the django oscar shopping cart needs to pass a valid return URL to PayPal in the API call at payment creation time.

BigCartel (Luna Theme): Shipping Rate Calculator not showing in Cart page

I'm using the Luna Theme with Big Cartel, site here: http://legencrew.bigcartel.com
I'd like my Cart page to show the shipping rate calculator which is already included in the theme. The weird thing is that I can successfully preview this feature in the Advanced Customization page, but for some reason it doesn't show up in the "live" website.
I think it is related with the variable "{% if cart.shipping.enabled %}", but I can't figure out what's going on.
I would be really thankful if someone could help me!
All of the variables on your Cart page are working correctly... this is happening because the store is using PayPal Express + Stripe for checkout, so the shipping and discount fields have been moved to the separate Checkout page. If you change the Checkout settings to use PayPal Standard you'll see the shipping and discount fields return. http://help.bigcartel.com/basics/settings/seamless-checkout/

Affiliate link tracking through Paypal

A company I help out have signed up to sell their magazine and newspaper products via an online affiliate.
The affiliate link directs users to a payment page on the client site, but they are using paypal for payments which as you know takes you away from the site.
I'd updated the paypal accounts to redirect back to the client site, where the affiliate tracking code sits, but I believe because we go off to paypal in the middle of the payment, no tracking is sent back.
Essentially, I need Paypal to send a specific code (in this case the merchant ID) and the order value when it redirects.
What would be the best way of doing this?
Thanks
Tom
I would send the affiliate ID in the CUSTOM parameter of your PayPal request and then setup an IPN solution to log the transaction in your database accordingly.
The CUSTOM parameter will come back in IPN so you can easily update your system with the affiliate ID.

Virtuemart, force user registration/login before checkout

I'm creating a site with VirtueMart 2.0 and Joomla 2.5.
Anyone can add a product to the cart, but I want to force the users to login/register before they go to the "Cart page/Chekout page".
Someone knows how can I do that?
In the Virtuemart Configuration Panel, on the "Checkout" tab, there are 2 checkboxes that you will want to set:
On checkout, ask for registration
Only registered users can checkout
