Fixing Autoload Errors When Installing WeltPixel Extensions from Magento Marketplace

You may encounter an Autoload Error during installation from the Magento Marketplace if both the standalone extension and its dependency pack (the package name ending with -theme) are selected.

Normally, installation should work whether you select only the standalone extension or both the extension and its dependency pack.

However, if you do see an Autoload Error, you can resolve it quickly via SSH by removing the -theme dependency pack.

Quick Fix (General Steps)

1. Connect to your server via SSH and navigate to your Magento root.
2. Remove the dependency pack that ends with -theme using Composer.
3. Run Magento setup upgrade.
4. Disable maintenance mode (in case it was enabled by the installer).

• composer remove weltpixel/m2-weltpixel-owl-carousel-slider-theme
• php bin/magento setup:upgrade
• php bin/magento maintenance:disable

Example 4: WeltPixel Google Analytics Enhanced Ecommerce Tag Manager

Commands to run:

• composer remove weltpixel/m2-weltpixel-google-tag-manager-theme

Notes

• Ensure you selected the correct package(s) for installation. If both the extension and its -theme dependency are installed and you get an error, remove only the -theme package.
• After completing the steps, re-check the extension status in your Magento Admin and proceed as needed.
