I can connect to LinkedinAPI but error says Consumer_Key_Unknown

[GoogleCodeExporter]

What steps will reproduce the problem?
1. use my demo.php as per your constructions
2. click connect to linkedin
3. Error is returned saying consumer_key_unknown

What is the expected output? What do you see instead?
I wanted it to authenticate the install of simple-linkedinphp and Oauth but it 
says my consumer key is unknown. I put the key and secret key in every php file 
where there was an array.. I triple checked and I am using the right keys and 
linked in's site says the project is active.

What version of the product are you using? On what operating system?

3.2.0

Make sure you get rid of the '<' and '>' symbols in the $API_CONFIG associative 
arrays.
