TYPO3 Core

How do I update my TYPO3 core correctly? I tried to overwrite my sysext with the sysext from the latest TYPO3.CMS master branch, but that didn't solve my probleme.

Here is my TCA for downloads in products class

'downloads' => array(
            'exclude' => 1,
            'label' => 'LLL:EXT:mb_products/Resources/Private/Language/locallang_db.xlf:tx_mbproducts_domain_model_product.downloads',
            'config' => array(
                    'type' => 'inline',
                    'foreign_table' => 'tx_mbproducts_domain_model_downloads',
                    'foreign_field' => 'product',
                    'maxitems'      => 9999,
                    'appearance' => array(
                            'collapseAll' => 0,
                            'levelLinksPosition' => 'top',
                            'showSynchronizationLink' => 1,
                            'showPossibleLocalizationRecords' => 1,
                            'showAllLocalizationLink' => 1
                    ),
            ),
        ),

and here the download TCA

Your TCA for the downloads table does not contain the field product referenced in 'foreign_field' => 'product'

Also your 'types' entry in the download TCA should start at '0' as that's the default entry and you don't have any type field configured

Thanks a lot for your support.

We updated to 7.6.2 today and it's working now.

Anyway I added product to my downloads TCA and changed the 'types' entry to 0. ext:Extension Builder set it to 1 by default.
