I followed the steps provided in the link above, yet I'm still encountering the following issue:
It seems like you are using Apache under Windows as Webserver. osCommerce will only work under linux.
I am using the XAMPP version 'https://sourceforge.net/projects/xampp/files/XAMPP Windows/8.2.12/xampp-windows-x64-8.2.12-0-VS16.zip/download'.
Do you have any suggestions or ideas to resolve this?
