Sul mio forum ( http://bmws1vc.altervista.org/forum/ ) che usa Invision Community v4.3.1 è apparsa la seguente scritta nel pannello amministratore:
Public Display of PHP Errors Enabled
The display_errors PHP configuration option is currently enabled on your server, which is not recommended for production environments and we recommend disabling it. If you do not manage your server yourself, your hosting provider will be able to assist with this.
