.. include:: /Includes.rst.txt ========================== TYPO3 Exception 1440754980 ========================== .. include:: /If-you-encounter-this-exception.rst.txt The option "source" is required and must not be empty ===================================================== This happens in 9LTS if you use ExtensionManagementUtility::addModule() with 7LTS parameters. Instead of :: 'labels' => [ 'tabs_images' => [ 'tab' => 'EXT:someext/Resources/Public/Images/icon.svg', ], 'll_ref' => 'LLL:EXT: someext/Resources/Private/Language/locallang_mod.xml', ] you need the 8LTS+ parameter type :: 'icon' => 'EXT: someext/Resources/Public/Icons/icon.svg', 'labels' => 'LLL:EXT: someext/Resources/Private/Language/locallang_mod.xml'
