If your PHP script does not work, this can have several total causes. First, we always recommend to check the error message with the provider of the software or the developer. Unfortunately we cannot guarantee support for scripts and applications.
Important to know: Our servers all run PHP version 5.x or higher. The current version is 8, which you can download on the official PHP page. Of course, it can happen that some older PHP variables for PHP 4 or lower are no longer supported. We have deactivated these for security reasons and recommend as mentioned above at least to change to version 5 or preferably to the current version.
These are mainly the following variables which are no longer supported:
$HTTP_POST_VARS
$HTTP_GET_VARS
$HTTP_SERVER_VARS
$HTTP_SESSION_VARS
which are determined by the variables
$_POST, $_GET
$_SERVER, $_SESSION
need to be replaced.
If a page or form does not work, please search (find/replace) the PHP scripts. Also for security reasons, we were subsequently forced to disable the PHP function Allow URL fopen (allow_url_fopen) and switch it to OFF.
Another recommended place to start is the PHP Manual Contribution Guide. Here you can find all important information and the complete documentation of PHP itself. You can also download the complete documentation in different available languages.
If your PHP script does not work despite these measures, you are welcome to ask us for advice. Use our support form for this.
