There are two issues here. One is that there's an error going on in the script. The second is the error handling isn't working properly. For the latter, you don't mention what version of PHP you're using, but I expect the warning in the box applies: https://www.php.net/manual/en/function.set-error-handler.php

Remove the last parameter from the my_error_handler() definition, as well as the use of that $e_vars variable within it. 

Once you fix that, you should properly see the actual error that's happening on the page.

Hi Larry,

Thanks for your responding.

I have removed the last parameter from my_error_handler()

From there error messages, you have two issues to resolve. The first is you haven't configured a local mail server. The second is your error handling script still references the $e_vars variable, which it no longer has defined as an argument.
