Sometimes it’s necessary to add some custom areas / keys to the Typo3 configuration ($GLOBALS[‘TYPO3_CONF_VARS’]). In my case I needed some auth-data for a Magento / Typo3 crossover in a curl call. The problem is: If you made manual changes in the typo3conf/LocalConfiguration.php , after a configuration save over the install tool, all changes will be […]
From time to time PHPStorm’s code completion stops working correctly (v 7.1.x). You’ll get no more hints and error positions will keep their marking although you fixed them.
