TYPO3 Core

Hi

Yes, this was tested on the current master and the site configuration in the example above looks like this:

rootPageId: 1
base: /
languages:
  -
    languageId: '0'
    title: English
    navigationTitle: ''
    base: /en/
    locale: en_US.utf8
    iso-639-1: en
    hreflang: ''
    direction: ''
    typo3Language: default
    flag: gb
    enabled: true
  -
    languageId: '1'
    title: German
    navigationTitle: ''
    base: /de/
    locale: de_CH.utf8
    iso-639-1: de
    hreflang: ''
    direction: ''
    typo3Language: default
    flag: de
    fallbackType: strict
    fallbacks: '0'
    enabled: true
errorHandling: {  }
baseVariants: {  }
routes: {  }

I can reproduce it with 10.0.0-dev (latest master) using the steps in the description.

Same problem on a 9.5.4 installation

The issue seems to be located in the class PageLinkBuilder which returns an UnableToLinkException (Unable to link "|": Default language of page "2" is hidden, so "|" was not
linked.).

As far I could see the exception is thrown in...

        if ($languageOfPageRecord === 0 && GeneralUtility::hideIfDefaultLanguage($page['l18n_cfg'])) {
            throw new UnableToLinkException('Default language of page  "' . $linkDetails['typoLinkParameter'] . '" is hidden, so "' . $linkText . '" was not linked.', 1529527301, null, $linkText);
        }

$languageOfPageRecord is zero because $page gets not overlayed due missing $conf['language'].
