Problem with returning info from paypal - 1.3.7 upgrade, express checkout

issue with Paypal - could be due to an additional MOD I've added, but....

appears on confirmation page after entering test CC info at paypal site -

any ideas? Earlier, I had a conflict while using a discount mod - I can reproduce that if required for debug -

thanks in advance -

Have you tested on a clean install?

sadly - - no. I was hoping to cheat & just add updated files without having to redo my CSS & other templates & mods all over again.... wishful thinking that it was an easy fast fix

Ah, well - I'll give that a whirl & post results. After new year's... :lamo:

I'll bet Graffi is having the same issue I am having.

The errors point to the tax module. So I removed everything related to tax in the Location / Tax area of Admin. The problem went away.

A clean install with out setting up taxes does not show this issue.

Silly question- is Gzip on or off on your server?

Gzip = 1 (on)

Dennis-

If you turn it off does the error persist?

Here is what I see. If Gzip is off the error shows all the time. If Gzip is on the only time the error shows is if I charge tax on shipping. Hope this helps

By default ... if you have GZip set to 0 but then test your site at:

http://www.whatsmyip.org/mod_gzip_test/

NOTE: you need a full URL to test like:
http://www.my_domain.com/index.php

Does it test as GZip On or Off when you have GZip turned OFF in your Zen Cart Admin?

How about if you have GZip ON in your Zen Cart Admin?

Yep, it test as on and off as I switch it on and off.

What version php do you have on your server?

PHP version 4.4.4

Only thing I am seeing at the moment is your Server API is CGI vs Apache ...

For giggles ... did you try a clean install without an changes from the current download of Zen Cart ... there was a minor change after xx number of downloads that isn't a major change and should not be related to this ...

Changes are noted here:
http://www.zen-cart.com/forum/showthread.php?t=54615

I did, but to be sure I am going to get the download again and place into usa3. Same user and pw. I will write back when complete. I predict the clean install will work perfect until I add a tax to product or shipping.

That is what I am afraid of ... but what the heck ... let's try it ...

NOTE: Clean install means ... can you toss in the demo data vs upgrade your existing database? :smile:

Yes demo data and my paypal stuff. Will not be an upgrade of production data.

Thanks ... just checking ... :cool:

New / Clean / Fresh install as agreed. Only one changes to start the Paypal express account. Purchase "Sample of Product General Type" with no errors.

Changed the tax zone from FL to TN. Purchased the same item above, with tax. No errors.

Added tax to shipping "Per Item". Purchased the same item above, with tax. Boom / Broke

Thanks Dennis. I think we know what to look at now.

Big Grin! :D
