Checkout, Login, and Email Notification Issues on CS-Cart 4.11.3

General

Hello everyone,

We are currently experiencing a serious issue with all of our websites running CS-Cart 4.11.3. The following issues are happening across all sites:

  • Checkout process is not working: Users cannot complete their purchases.
  • User login is broken: Visitors cannot log in to their accounts to place orders.
  • Payment methods not displaying: None of the payment options are showing up during checkout.
  • Order notifications: We are receiving multiple email notifications for the same order, and the information in them is incomplete.

We have been trying to resolve this issue since yesterday but haven’t been successful, as no settings related to the checkout process have been changed.

Additionally, when I checked the browser console, I encountered the following errors:

  1. JQMIGRATE Warning:
  • “JQMIGRATE: Migrate is installed, version 3.0.1”
    This suggests that an older version of jQuery or deprecated jQuery functions might be in use. Could this be causing any issues with functionality?
  1. POST Request Failure:
  • “Administration panel net::ERR_CONNECTION_CLOSED”
    This error indicates that the connection was unexpectedly closed while attempting to update the order status. The server seems to be rejecting the request.

Has anyone else encountered similar issues, or does anyone have suggestions on how to resolve this? We would greatly appreciate any help or advice.

Additionally, if possible, we would like to revert the websites to the state from March 19th, when everything was still working fine.

Thanks in advance for any help or suggestions!

Maybe check with your hosting company to see if anything in your hosting environment changed, like PHP version or such. Something like that seems the most likely since it happened without you changing anything on the site.

Agree, looks like server should be tuned for CS-Cart

At first, find the CS-Cart requirements article in the official documentation and forward it to your hosting support

Thank you both for your suggestions. I’ve already contacted the hosting provider, and they’ve assured me that nothing has changed on their end, such as the PHP version or any server settings.

However, I am still facing an issue where order notifications are being sent multiple times. The same order appears three times in the admin panel, and both administrators and customers are receiving the same notification three times as well.

I was wondering if you have ever encountered a similar issue? If so, do you have any suggestions or guidance on what might be causing this, and how we can go about resolving it?

Thanks again for your help, I really appreciate it!

I did have a problem with multiple emails being sent per order, and inventory being deducted multiple times per order. This was related to the Stripe addon. I had to hire a developer to fix it.
