Paypal - session logged out - please sign in again

DR.Byte - If I was to check with the customer concerned - and gave you his email address and my store details - would that help in finding out the problem?

It's possible that having that information may be helpful. If I could log into your store using his account to do a test, maybe we might get even further. You can PM me with whatever details your customer is comfortable sharing privately. Confidentiality assured of course.

I have contacted him and just awaiting his reply.

Just a thought - I have both Paypal IPN & Paypal Express checkout both installed and active - is it possible that they are "confusing" each other on ocassions?

A patch was just released which updates a number of things.
While this timeout issue wasn't specifically addressed, several overall improvements were made, and may help.

If you can test and post back, it'll give me a better feel for what's left once I can look at it, probably tomorrow.

I have install the update.
I tested the setup myself and there were no problems with either the Paypal express nor the Paypal IPN - both transactions went through smoothly.

I asked my customer Matthew, who is having the problem using my store and this was his reply to me:

When trying with the yellow checkout paypal button it says
This session contains invalid data.
And when using the Paypal IPN number it says the same thing as above.

Sorry it doesnt appear to be working again

Have you tried to email him directly - he has no problem with you contacting him?

A brief update ... your site is using URL masking, which is no longer compatible with PayPal's website-payments-standard product. The PayPal IPN interface checks the URL in the browser, and if it's not a paypal address, it blocks the transaction in order to prevent spoofing and fraud.

Turning off URL masking on your site should resolve the matter, at least according to PayPal tech support's suggestion after looking at your site.

Naturally, you could retain your URL masking if you chose to use PayPal Express Checkout instead of PayPal IPN module.

YES YES

I altered the web forwarding on the domain names from framed to un-framed, which had the effect of show the true url on the browser and PROBLEM SOLVED.

It was as stated above, the url shown was not as PayPal expected and their security system prevented the transaction from going further. It was only happening to a few people as most were, by chance, going through using the path that PayPal recognised and not one of the "covered" routes.

Hope this helps other with a similar problem
Thanks to DR Byte - you're good !
