IPN Error - Paypal transactions not from the store

[NeoX]

Hi SmfHacks.com,
I have a problem with store and IPN.
A week ago for error    I have made a Paypal transactions not from the store and now with normal smf store there are problems because transactions not being recorded, with IPN link I have this error:

Array ( [_php] => [start] => 0 ) Array ( [_php] => [start] => 0 ) Error

For now I can use the send free product link to send download links but how can I correct this error and come back as before??
Here Store_debug.txt log:

Is that an error log from a real paypal transaction?

[NeoX]

Yes it's  a real paypal transaction....

[SMFHacks]

Is that all that is in your debug log?
If you visit that page directly that will be recorded since there is not transaction.

Next question do you have paypal IPN url set to your storeipn.php or storeipn2.php to path and that you have IPN enabled under paypal settings.

Thank you,
ok this is debug log with last info:

http://www.charactersforum.com/store_debug.txt

Here also paypal debug:

http://www.charactersforum.com/paypal_logs.txt

Yes paypal IPN url enabled to path where storeipn2 is installed, before Paypal transactions not from the store everything worked perfectly.
In paypal IPN details there is 500 HTTP error and the transaction delivery status in attempting after 15 attemps in about 3 days.
The  transaction made for error a week ago in paypal IPN details there is no error.... strange thing, something happened in the database after this transaction not from the store?

Thank You.

According to those logs it's not getting past insert transaction is that correct? You do not see any transactions recorded under view transactions in the store.

First check your forum's error log and see if you can see any database errors around August 1, 2011, 11:21 am

If not try this attached updated storeipn2.php adds another log entry right before an entry is inserted in the database.
