Generate a PHP Error
It may seem odd to deliberately create PHP errors, but it's a useful test. PHP errors do occur from time to time in both Joomla and in extensions, especially if you have old extensions and upgrade your PHP version. You should make sure that your site can handle all of these errors properly, i.e. without alarming the user, and preferably sending you an email to inform you of the error.
Create a menu item of type LADkit, Generate an Error. If you do this on a live site, create the menu item on a hidden menu. The front end view looks like this.
Select the error you want to generate and click the Go button. Test all of the errors and make sure you are happy with the way your site handles them. The results depend on the Error Reporting setting in Joomla Global Configuration, and the error handling provided by your site template. You might be surprised how badly some templates handle some of these errors.
