Solution

  • About the exception you are getting: It seems you stumbled upon a bug which is fixed in latest version 7.6.26. Please update to the latest version. Make sure you follow the correct procedure for updating.

    If the problem still occurs, clear the system cache in the install tool.

    More general hints:

    • Always keep your TYPO3 system up to date. Either subscribe to the typo3-announce mailing list or keep track of the channel #announcements in the typo3 slack workspace. That way you will be notified as soon as a new TYPO3 version is released. If you don't have access to the TYPO3 slack workspace yet, register for an invite.
