I have been unsuccessful in connecting to my XAMPP server from a remote pc. I have checked my httpd-xampp.conf file and there is no LocationMatch section to input the "Allow from All". Not sure if this part just doesn't exist with newer versions of XAMPP, or if it is located in a different file?
Check on log file for more details about get 403, is first step to start investigate if problem is dir/file permission or httpd.conf misconfiguration
