[TYPO3-english] PayPal IPN works in 4.3 but does not work in 4.5?

[Scotty C]

Hi everyone,

I'm building a PayPal ecommerce site and having the weirdest problem. In making 
a purchase and for security purposes, PayPal uses a verification process call 
IPN. The way it works is:

- Customer makes a purchase at www.10minutewebsite.ca/?subscriptions
- PayPal sends a request to my server at 
www.10minutewebsite.ca/?paypal_ipn_verify to verify
- My server uses a PHP script to receive/reply back to PayPal

Now for the weird part: In v. 4.3, the process worked just fine. I upgraded to 
4.5.2 LTS and PayPal is reporting  a 403 error accessing the 
www.10minutewebsite.ca/?paypal_ipn_verify page.

I can reference the page directly in a browser. I checked with my server host 
people and they say that there's nothing wrong with the server/firewall causing 
this block - they insist it's due to 4.5.2. Additionally, they gave me this 
message in 'typo3conf/deprecation_6e7b3daa61.log' file during the ipn verify 
process.

I have a feeling this is a relatively simple permissions issue, but I have that 
"needle in a haystack" feeling. Can anybody help please?

Thanks so much as always in advance,
