From the XAMPP control panel if for Apache I click [Logs] and select PHP (php_error_log) notepad opens saying it can't find the log file. I am sure this used to work, and am a bit puzzled by the name php_error_log, why not php_error.log.
I have tried changing php.ini by setting error_log = C:\xampp\apache\logs\php_error.log but it has not made a difference.
I would be happy to just go back to the default behavior of php logging to the apache error.log and not get an error on clicking the php_error_log.
BUT ideally I would like php errors to go to php_error.log with the control panel being able to find the log.
