WeltPixel Backend Module Downgraded After Composer Update When Using Multiple Repositories

Problem

After running a Composer update — for example, when installing or updating the GA4 PRO module — you may notice that the weltpixel/m2-weltpixel-backend module is unexpectedly downgraded to an older version. Running bin/composer show weltpixel/m2-weltpixel-backend --all confirms that the currently installed version is lower than what is available from the WeltPixel repository.

This happens when your composer.json includes both the WeltPixel Composer repository and the Magento Marketplace repository (repo.magento.com). Because the Magento Marketplace also hosts a copy of the weltpixel/m2-weltpixel-backend package, Composer resolves the package from whichever repository is listed first. If the Magento Marketplace repository appears before the WeltPixel repository, Composer will use the Magento-hosted version, which may be behind the latest release available from WeltPixel.

Solution

There are two ways to fix this, depending on whether your project still requires the Magento Marketplace repository.

Option 1: Remove the Magento Marketplace Repository (Recommended)

If your project does not require any packages from repo.magento.com (e.g., you are not using Adobe Commerce or Magento Marketplace extensions beyond WeltPixel), you can remove the Magento Marketplace repository entry from composer.json entirely. This eliminates the conflict.

Option 2: Move the WeltPixel Repository Above the Magento Marketplace Repository

If your project does require repo.magento.com, ensure the WeltPixel repository is listed before it in the repositories section of your composer.json file. Composer resolves packages from repositories in the order they are listed, so placing the WeltPixel repository first ensures it takes priority.

Incorrect order (causes downgrade):

"repositories": [
    {
        "type": "composer",
        "url": "https://repo.magento.com/"
    },
    {
        "type": "composer",
        "url": "https://weltpixel.repo.packagist.com/YOUR-REPO-KEY/"
    }
]

Correct order (resolves latest version from WeltPixel):

"repositories": [
    {
        "type": "composer",
        "url": "https://weltpixel.repo.packagist.com/YOUR-REPO-KEY/"
    },
    {
        "type": "composer",
        "url": "https://repo.magento.com/"
    }
]

After making either change, run the following commands to update the module and apply the changes:

bin/composer update weltpixel/m2-weltpixel-backend
bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento setup:static-content:deploy
bin/magento cache:flush

Verification

Confirm that the latest version of the Backend module is now installed by running:

bin/composer show weltpixel/m2-weltpixel-backend

The versions field should show the latest available release as the currently active version (marked with *). No downgrade messages should appear the next time you run composer update.
