Peerfly - LeadImpact - Prosper202 - (PHP Redirect Not Working)

Hello Warriors,

Good day!

I am working to run Peerfly CPA offers, Lead Impact as my traffic source and Prosper202 as my tracking tool.

I am not sure why the PHP Redirect in my landing page is not working properly. It is not redirecting to the offer that I prefer.

This was what I did:

1. Logged in to prosper202 (done with the setting up of traffic sources, categories, and campaigns)
2. Clicked "Landing Pages"
*2.1 Landing Page Type
**2.1.1 Simple (One offer on the page)
3. Selected Affiliate Network
4. Selected Campaign (offer)
5. LP Nickname
6. Landing page URL (mydomain.com/lander1)
7. Clicked "Get LP code"
8. Clicked "Simple"
*8.1 Aff Network
*8.2 Campaign (offer)
*8.3 Method of Promotion (Landing Page)
*8.4 Landing Page (Selected LP)
*8.5 Generated Tracking Link
*8.6 Copy the javascript in the first box.(Prosper202 - Inbound Javascript Landing Page Code)
*8.7 Paste it in my landing page
**8.7.1 Opened my LP's file (notepad)
**8.7.2 Searched for closing head tag, "</head>" without a quote and made a space.
**8.7.3 Pasted the javascript from prosper202.
**8.7.4 Saved
9. Got notepad and named it (redirect.php)
*9.1 Copied the entire php code from the second box (prosper202 - Landing Page: Outbound PHP Redirect Code
*9.2 Paste it in my notepad with a name "redirect.php"
*9.3 Saved.

10. Opened my LP's file (notepad)
*10.1 Searched my Call To Action and Image link
*10.2 Entered my landing page link with "/redirect.php" (mydomain.com/lander1/redirect.php)
*10.3 Saved
11. Uploaded to server(public_html) using Filezilla (LP file - index.html and the redirect.php)
12. Got back to prosper202.
13. Clicked "Get Links"
*13.1 Got Text Ad Code For (Chosen Simple Landing Page Setup)
*13.2 Selected Affiliate Network
*13.3 Selected Campaign (offer)
*13.4 Method of Promotion (Landing Page)
*13.5 Selected Landing Page Name
*13.6 Selected Ad Network
*13.7 Selected Account Name
*13.8 Clicked "GENERATE TRACKING LINK"

14. Copied the generated tracking link
15. I test it:
*15.1 Put the generated tracking link in my address bar
*15.2 Clicked the Call to Action Link and the Images (It should redirect me to the offer) BUT IT DIDN'T.

I saw that I must have PHP installed on my server for the PHP Redirect to work.

I checked my Cpanel and saw that the version of my PHP is 5.4.26 - meaning, there is PHP installed on my server and the PHP Redirect should work - BUT IT DIDN'T.

What did I do incorrectly? And how to solve it?

Please help...

Thanks!
