TYPO3 Core

Error:¶

While upgrading to 6.2.15 I have got the following error in the Install-tool when trying to use the Upgrade Wizard:

Uncaught TYPO3 Exception
#1: PHP Catchable Fatal Error: Argument 2 passed to TYPO3\CMS\Core\Utility\GeneralUtility::array_merge() must be of the type array, null given, called in /var/www/vhosts/<dom.tld>/sub_test/typo3conf/ext/t3skin_improved/ext_tables.php on line 44 and defined in /var/www/vhosts/<dom.tld>/sub_test/typo3_src-6.2.15/typo3/sysext/core/Classes/Utility/GeneralUtility.php line 1795 (More information)

(/Full details below)

Cause:¶

If I track it correctly this is raised by the arry_merge function in sysext/core/Classes/Utility/GeneralUtility.php (line 1795) which does not check if any part of the two arrays to merge is null.

Ans this seems to be the case when the function is called from the t2skin_improved, which (possibly) does it due to repetitive/recursive use of the statement in typo3conf/ext/t3skin_improved/ext_tables.php at line 39.

        // some special icons for container sysfolders
        $path_icons_original = '../' . TYPO3_mainDir . 'gfx/i/';

        $ICON_TYPES = t3lib_div::array_merge(array(
            'fe_users' => Array('icon' => $path_icons_original . 'modules_fe_users.gif'),
            'shop' => Array('icon' => $path_icons_original . 'modules_shop.gif'),
            'board' => Array('icon' => $path_icons_original . 'modules_board.gif'),
            'approve' => Array('icon' => $path_icons_original . 'modules_approvals.gif'),
        ), $ICON_TYPES);

        if (t3lib_extMgm::isLoaded('direct_mail')) {
            $ICON_TYPES = t3lib_div::array_merge(array(
                'dmail' => Array('icon' => t3lib_extMgm::extRelPath('direct_mail') . 'res/gfx/modules_dmail.gif'),
            ), $ICON_TYPES);
        }
