Hi folks,
as you might have recognized, with OXID eShop version 4.9.0/5.2.0 we ditched the support for the PHP server settings magic_quotes = on, these must be set to “off” from now on directly on your server. If you don’t know how to do it, please turn to your hosting provider for help.
If you set up a new installation on PHP 5.3, you cannot pass the first setup step for this reason if magic_quotes_gpc = on. If you updated from a previous version it might happen that you’ll find strange backslashes in your texts entered into the database.
