When trying to add a new translation of a page I get the message
Sys language UID “1” not found valid!
My log file says
[ERROR] request=“afe7370c60419” component=“TYPO3.CMS.Frontend.Configuration.TypoScript.ConditionMatching.ConditionMatcher”: Expression could not be parsed. - {“expression”:“"1" == "1"] && [page["backend_layout"] == "pagets__home"”}
My site config.yaml has this language setup
