CS-Cart and Multi-Vendor 4.3.1 Released


We’re happy to present to you the final CS-Cart and Multi-Vendor 4.3.1 release.

CS-Cart 4.3.1 is faster and more feature-rich than any other CS-Cart version.

Speed Boost

CS-Cart 4.3.1 is fast:

  • SQL query optimization speeds up product search and filtering.
  • Optimized caching makes the search faster, if you call the same search twice. Storefront pages also load faster on the second visit because CS-Cart 4.3.1 caches the content during the first visit.
  • CS-Cart 4.3.1 supports Alternative PHP Cache. This technology speeds up PHP scripts on your server. Even well-optimized websites load with a delay because it takes time to execute PHP scripts. APC cache shortens this delay.
  • JavaScript code was moved to the bottom of pages so that the code doesn’t slow down page loading. Store pages now load faster on the first visit.

Functionality Improvements

Thanks to the community feedback during the beta testing, we’ve fixed nearly 150 bugs. Check out the changelog for all improvements and fixes.

Multi-Vendor: Fully Featured Vendor Storefronts

In Multi-Vendor 4.3.1, vendors make their own fully functional storefronts with categories, filters, search by vendor products, and more. Vendor pages in previous Multi-Vendor versions lacked most of these functions.

A vendor page in Multi-Vendor 4.3.1 looks like a vendor page on eBay or Amazon:

New Blog Add-on

The Blog add-on lets you create a fully functional blog inside your store. Keep your customers informed by posting news and special offers in your blog.

Upgrade Center Refinements

The Upgrade center in CS-Cart 4.3.1 has become more user-friendly. The Upgrade center will guide you through the upgrade process, showing the process in detail.

We improved backup and restore. If something goes wrong during the upgrade, you’ll be able to roll back safely.

Export and Import Enhancements

In CS-Cart 4.3.1 we’ve introduced a long-awaited feature—export and import of option variants, option combinations, and option exceptions. This feature simplifies catalog updating and stock accounting.

For example, you sell a T-shirt model that comes in different colors and sizes. You need to track the exact number of blue T-shirts of size M at your warehouse. These T-shirts have a combination of two options: blue color and M size.

Export product data with option variants and option combinations from your store. Then, import this data to the stock accounting software. You can now track the actual number of blue, medium-size T-shirts at the warehouse.

Bestsellers & On-Sale Products Add-on Expanded

New functionality allows you to show similar products on a product details page. We’ve also added an ability to create pages with all bestsellers, on-sale, new, and final sale products.

Other Enhancements

CS-Cart 4.3.1 has a bunch of smaller enhancements, including:

  • Faster checkout
  • Easier navigation
  • Custom layout
  • Your own logo and favicon for each style
  • Displaying products immediately after choosing a filter
  • Ability to define a user group for a user via API
  • Improved protection from CSRF attacks
  • API 2.0 by default

How to Get 4.3.1

Download the CS-Cart or Multi-Vendor installation package.

Purchase a commercial license to get all features and support. Before purchasing a license, you can try CS-Cart or Multi-Vendor for free for 30 days. You can use CS-Cart for free even after the trial, but you’ll only have access to a limited set of features.

If you already have a license and an active upgrade subscription, download your personal installation package from the File Area in your Help Desk account.


License owners with active upgrade subscriptions have two options for upgrading from 4.0.1 and higher to 4.3.1:

  • Upgrade center. Go to your admin panel, Administration → Upgrade center, and click Download Install.
  • Store Import. To upgrade from CS-Cart 3.0.6 and earlier (except the Community edition) to the current version install CS-Cart 4.3.1 and import your store.

Please ask any questions regarding CS-Cart and Multi-Vendor 4.3.1 in the comment section. How do you like the new features? We greatly appreciate your feedback!

    I’m using cs-cart 4.2.4, and I don’t see the upgrade package in Administration → Upgrade center (already Refresh packages list).
    It gives me “No upgrades currently available”.

    • Yan Kulakov says:


      We’re planning to launch the upgrade within a week. We will be limiting the number of downloads to avoid server overload.

      Thank you for your patience.

  2. I completely migrated my site to a new version of CS-Cart

    The main online store has two additional storefront.

    I used the export and import functions for the transition to the new version.
    All work was carried out on the local computer.
    Then, a new version of an online store was offered for hosting, instead of the old version.

    All 3 stores began to run faster by almost 2 times.

    Now speed 76/100 for mobile devices and 88/100 computers/
    Previously, the download speed was 37/100 for mobile and 44/100 for computers

    It’s great!

    Thank you very much!

      We’re planning to launch the upgrade within a week. We will be limiting the number of downloads not to overload our servers.

      Thank you for your patience.

  4. Артем says:

    Good afternoon. It’s already the end of the week. Are you going to launch the upgrade today?

  5. Geert says:

    Still no update visible in my upgrade center.
    Are there problems with releasing?

    • Yan Kulakov says:

      Hello Geert,

      Right now we are limiting upgrade package downloads not to overload our servers. If everything is alright, we will launch the upgrade for all without limitations within a couple of days.

      Thank you for your understanding.

  6. Hans Hernik says:

    dont upgrade – my whole site has crashed! I did upgrade from the link that apperaed when I opened my control panel. Store is closed now and backup has been deleted. GREAT! I am furious!

    • Yan Kulakov says:

      Hello Hans,

      Sorry to hear that something is wrong with your store.

      Our support team asked you to give them an FTP access to your store. They will check it and solve your problem as quickly as possible.

      Here’s a tip: If you experience any issue, give an FTP access to our support team immediately after the issue occurs. This can speed up the process.

      Hope the support team will resolve your issue soon. Have good day!

  7. Артем says:

    Good afternoon,

    Could you please tell me how you distribute upgrades? Last time you told me that the upgrade will be available within a week, but I guess that you are still limiting upgrade package downloads.

    • Yan Kulakov says:

      Hello Артем,

      I guess you are running the russian version? The upgrade for the russian version of CS-Cart is being prepared right now. Most likely, the upgrade for the russian version will be available by the end of this week.

      I misunderstood you before. I was telling you about the upgrade for the international version of CS-Cart. It’s already out. But the upgrade for the russian version is delayed a bit. Sorry for misunderstanding.

    What are the steps for installing v4.3.1? The blog says “Go to your admin panel, Administration → Upgrade center, and click Download” but there is no “Download” option, only “Install”. “Install” eventually Closes the store but nothing else. What are the proper steps?


    • Yan Kulakov says:

      Hello lee,

      That’s right, the Install button is what you need. But unfortunately, we are facing some issues with the upgrade right now. We are fixing them at the moment and soon the upgrade will work fine.

      Please, contact our support team via your Help Desk account and give them a temporary FTP access to your store. They will solve your issue with the upgrade.

      Sorry for the inconvenience.

    I see there are a lot of comments here. Could you please tell me when the upgrade to 4.3.1 (russian build) will be available?

    • Yan Kulakov says:

      Hello Maria,

      The upgrade to 4.3.1 of the russian build has been already tested. We are planning to launch it this week. Maybe in a couple of days if there is no more issues.

      Have a good day!

  11. Ariel Cast says:

    Thanks ! Update now !

  12. lee says:

    Is the 4.3.1 (U.S. store) install ready? Is it safe/ready for me to press the “Install” button?

    • Yan Kulakov says:

      Hello lee,

      The most severe issues have been fixed. You can upgrade now.

      But there still could be an issue while CS-Cart downloads the upgrade package. If you see the “Error 500″ after you click the Install button, contact our support team via your Help Desk account. They will solve this problem in a moment.
