Troubleshooting

Caching

Sometimes inaccurate data is stuck in the Composer Cache. Please clear it.

Composer 2.0

Composer 2.0 changes the way repositories are prioritized. You can find more information on the Composer website. In this case, you can use the only attribute as:

["yoast-seo-for-typo3/yoast_seo_premium"]

So, your composer.js file should have a line like this:

{ 
"name": "example-site-com/typo3-website", 
"description": "TYPO3 Website", 
"repositories": { 
    "my-yoast": { 
       "type": "composer", 
        "url": "https://my.yoast.com/packages/" 
        "only": ["yoast-seo-for-typo3/yoast_seo_premium"]
}
