WampServer Fatal error - Maximum function nesting level

You may get this error message on a Windows configuration only (e.g. WampServer).

Error message: "Fatal error: Maximum function nesting level of '100' reached, aborting! in C:\wamp64\www\tng\tngconnect.php on line 157"

The error message is misleading (tngconnect.php) as this is a problem with the Windows PHP XDEBUG Extension (php_xdebug-x.x.x-x.x-vcxx.dll). The problem may be fixed by changing the configuration file php.ini located in the Apache directory

Finding the configuration file

Open file php.ini located in

[Your Wamp Directory]\bin\apache\[Apache Directory]\bin\php.ini

e.g. C:\wamp64\bin\apache\apache2.4.27\bin
