500 Internal Server Error during paypal/redirect.php

[Hypno]

When trying to do a test checkout (live mode and sandboxed) I get a 500 Internal Server Error.

I really need to get this fixed and I have already check this:

If anyone could help me figure out this issue that would be great!

Thanks!

Yes, the 500 error is there but it is not possible to say what is wrong without further info. Please post the relevant lines from the apache log.

@Hypno : I had the same issue as yours since I'm upgrading my PS shop to PS 1.3.2.3 (from 1.3.1.1).
Indeed the Paypal module version is upgraded also (from 1.6 to 1.7.1) while upgraging PS.
I resolved the issue by changing the CMOD rights of my PayPal directory to 755 (before it was set to 777, as noticed in the wiki), and I used the recursive option (subfolder & files).
Now it works on my side.
Hope it can help you.

I found the solution if your still having problems is changing your modules folders permission to 755 recursively(files and folders). Mine was set to 777 since prestashop tells you to do that on install, yet aparently its supposed to be 755.
