Donor info not showing up, nor campaign donations

Hi, just purchased the software, having some trouble. Trying to test Donation in PayPal sandbox, donor info not showing up in DB and also Campaign info is not updating after re-direct back to site. I've tried this fix from a similar post:

"=> This issue only happens in TEST MODE because It seems Paypal changes their testing API recently and Test Mode doesn't work very well these days. I modified the Paypal payment plugin alitle to make it works with Test Mode. You can get the file below, unzip it, upload to components/com_jdonation/payments folder. After that, Test It again and It should work !

Uploaded new file, still getting same problem. Suggestions please? Thanks.

Hi

I am sorry for lately response. Could you please submit a support ticket giving me administrator and FTP account of your site so that I can check and fix it for you ?

Would like to see the solution to this problem

The fix for Paypal Test Mode is added to latest version of the extension. Please upgrade your site to latest version of the extension, test it again and it will work as expected !
