Typo3 10.4.37
Updating from yoast_seo: 8.3.1 to 9.0.0
or
Updating from yoast_seo: 8.3.1 to 9.0.1

As soon as I select a page I get the following error.

Hoped 9.0.1 would have solved the issue.
But it seems to be something different.

Hi @Batman777,

Are you sure you flushed all the caches, through the Maintenance module or through CLI?
This is a dependency injection issue and flushing the caches with the dropdown flush actions is not enough.

[Batman777]

Sigh ... again a caching issue.
Thank you very much @RinyVT
This solved the issue!

[RinyVT]

Great! Glad it solved the issue.

I had the same problem. After flushing the caches with the adminmenu the typo3-backend and the frontend don't work anymore and I get this error on the white screen:
Fatal error: Class YoastSeoForTypo3\YoastSeo\DataProviders\OrphanedContentDataProvider contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (YoastSeoForTypo3\YoastSeo\DataProviders\OverviewDataProviderInterface::getData) in /kunden/84737_51427/webseiten/kgsfrankenforst2/typo3conf/ext/yoast_seo/Classes/DataProviders/OrphanedContentDataProvider.php on line 14

Hi @GitCybers,

Are you sure you are on the latest version?
Your error mentions a getData method but this method is nowhere to be found within the Classes/DataProviders directory.

The error also does not make sense because there is no abstract method within OrphanedContentDataProvider.
Which PHP version are you on?

I installed 9.0.1 and got the first error. After flushing in backend ajax arrors in backend. Then I installed 8.3.1 and then I got the php error.

After deleting the entry for the extension in PackageStates.php and deleting the extension the frontend and the backend work again. Then I installed the extension 9.0.1 again and it works.
