Paypal IPN problem - Not Working

[asphole]

Hello Everyone,

On Friday my zen cart site suddenly stopped completing paypal orders. I receive the payments but the orders are not copied into the orders table.

My webhosts switched of base64_decode() function that day for security purposes and this affected my sites. They switched it back on after a lot of complaints but my paypal ipn is still not working.
Could this be linked? Its very strange that it has worked for the past 12months with no problems and has only stopeed since the hosts security changes.

They have moved my sites to another server but the issue persists. I have enabled the debug option and I am not receiving alerts unless i access the IPN page directly.

I installed the view paypal stuck orders mod on Saturday but even that doesn't work. It fails with the following error: Catchable fatal error: Object of class shoppingCart could not be converted to string in /home/account/public_html/admin/view_stuck_paypal_orders.php on line 87

Line 87: $mysess = unserialize(base64_decode($stored_sessions->fields['saved_session']));


Note the base63_decode() again! It seams this would all relate to my hosts changes but i cant find out how to test/prove this. Unfortunately php is not my bag baby so ANY help would be HUGELY appreciated!

Turn off Debug-to-Email, and turn on Debug-to-File.
Then do a transaction.
Then download and zip all the generated log files, and post them for review.

The one-off emails will just confuse you and send you looking in the wrong place worried about things that don't show the big picture.


Keep in mind that PayPal has been having serious problems today.

Hi Dr Byte,
Thank you for your quick reply. I will do as you say now and post the results here asap. I did wonder if paypal was the cause but I have other sites working fine with paypal so ruled that out.
Will post again soon.
TIA.

I did the switch to log file only and made a purchase but no log files were created. I am convinced the paypal IPN simply isnt able to contact my IPN script. Any thought?
