No columns definition in TCA table¶

On possible cause for this is the use of old ext_tables.php/TCA configuration. Please see https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog/7.6/Index.html for the changes in TYPO3. Also, the TCA file must return the array, not only declare it, as would work before.
