I would like to debug a PHP (Fast-CGI) web application configured on ISPConfig 3 but a blank page is returned. Can I configure "Custom php.ini settings" or "Apache directives " (in Web Domain > Options) to enable debugging? If this is the right way, how can I do? Thanks.
You can enable verbose php error logging either in the php.ini file to enable it globally or in the "Custom php.ini settings" settings field to enable it just for this one website. You might also want to take a look into the error.log file of the website.
Thank you Till, I solved it by putting PHP: error_reporting=E_ALL; display_errors=on; in "Custom php.ini settings" field. Is it possible to limit the display to one (or more) IP address using fields "Custom php.ini settings" or "Apache directives "? Thanks again.
