Intermittent PayPal problem. Confirmation email and order details often absent.

[breezie1977]

Hi there, I know there have been a lot of posts about this and I've searched them all to no avail. My last resort is posting here.

I've had a zen cart store for several years now and have always used PayPal IPN with very few issues. Until recently when I upgraded from 1.3.8 to 1.3.9h and also changed the fileset of my database from Latin1 to UTF8 to handle Japanese characters properly.

80% of the times when people purchase, a notification comes through from PayPal that someone has paid me, but no order confirmation is being sent to the customer and hence no details of the order are being forwarded to me. The other 20% are fine.

Many people on this forum say PayPal Express Checkout is more stable and more modern. So I installed it and found that due to my "Wordpress on Zen cart" integrated blog (very important for driving new customers my way) there is a problem which renders this PayPal Express module unusable (10727 Shipping Address 1 missing). I can see no answers to this problem on this forum, just people saying it exists. So I'm left with PayPal IPN as my only option (unless anyone knows a workaround here?!).

The really annoying thing is that I can't recreate the issue. Every test order I put through goes through with no problems whatsoever. It doesn't seem to matter where the customers are in the world either, local or international the problem seemingly has no pattern. I've checked all the addresses people gave me and can see no strange characters. My site is based in Japan and customers ordering in Japanese all seem to go through just fine.

I've used the IPN check tool and got the following glowing results:

"IPNCHECK.PHP - Version 1.3.9

IPN TESTING - Response Received via CURL -- COMMUNICATIONS OKAY

IPN TESTING - Confirmation/Validation response with fsockopen(): FSOCKOPEN() RESPONSE RECEIVED - Communications OKAY

Default method likely to be used for communications is: CURL, with the fallback method being FSOCKOPEN if possible.

Script finished."

I've even removed all wordpress addons which handled the automatic processing of metatags as one thread on this forum said sometimes that causes issues. Still the problem persists.

Here's some logs from a recent English language transaction that went through on PayPal, but was ignored by Zen Cart. Obviously the customer's details have been changed before posting these files here but there were absolutely no strange characters or overly long fields.

Any help anyone?

Thanks in advance,
