	0 answers Post by phaby amardy on April 21, 2012 Hi, I am using window 7, the php scripts from web_app version-6.0 and up. As i was following along, i was making my own web store base o the information you were given. But whe i reach web-app version 6 in lecture my php scripts stop working, it displayed many errors. I even downloaded your webapp training files and i opened them in my browers it gave me the same errors as my web_app. this. Mainly it does not display the header, html and the images, and the config.php, is there any thin i can do to fix this?

	0 answers Post by Rory Demers on May 15, 2012 For those of you getting errors and warnings on the lesson files make sure that in whatever IDE or notepad you are using that you follow the file path exactly as stated in the config.php file when adding them to your IDE. My mistake was that I was copying and pasting the files from inside the versions folder and leaving out the file path web_app and version-6.0 which are in the config.php file. FYI: Also heads up on where he places the images folder going forward 6.1 and on.
