Help? (Invalid Parameter)?

[Rememberthemoments]

I wanted to clarify my previous post. I installed PayPal IPN to make sure that the issue wasn't with PayPal (since so many of us are having this issue and I know that myself and one other person had Express working properly before)

PayPal IPN worked for the transaction, but I am still receiving the same error message when I try to check out with PayPal Express.

I checked the PayPal status blog (posted at the top of this forum) and there have been no updates since Feb 8, so I do not believe that is the cause of the issue.

I removed PayPal Express and Intalled it again, reentering all of my API information, but I am still getting the same error message.

PayPal Express isn't working at all and PayPal IPN doesn't work for EChecks! HELP!!!!

Please stop multiple posting. It makes it very difficult to follow what has and hasn't transpired. Pick a thread and stay there. Thanks.

I have another thread regarding PayPal IPN (I have no preference to which PayPal module I use, but neither of them are working for me)

I apologize for the cross post on the other thread.

I would love help with figuring out the PayPal Express issue and will keep my comments to this thread.



The error message does not occur until you have completed the transaction.

If you would like to view the error message I have created this product (that only costs a penny) and you can choose Walk In from the shipping selection so that no shipping is charged)

I have spent the entire day trying to solve this mystery and am no closer to an answer than I was this morning.

Here is what I have tried (so that hopefully someone more experienced than myself can use this to problem solve)

***

I reinstalled the patch (no change)

I downloaded a fresh copy of 1.3.7, installed the patch. I received the same error message.

I canceled my API Signature and requested a new one. Then updated the appropriate information in the payment module.

***

This info, in addition to the fact that I made no changes to the code prior to it deciding not to work, makes me think that the issue lies either with PayPal or my Hosting site.

The original poster on this thread does not share the hosting site with me, which doesn't rule out the server issue, but makes it less likely than the one constant, which is PayPal

But if the issue was with PayPal I am assuming that there would be more reports of errors from other Zenners using PayPal Express.

I have run out of ideas...

If anyone has any suggestions on what things I should be asking my Hosting Company to make sure it isn't their issue I would appreciate it.
They have already verified that they havenot made any upgrades or changes to the server in the last 24 hours (when the problem started) and that the cURL is enabled.

I have a call in to paypal. I explained to him that we all have different severs and none of us changed our sites so the only common denominator is them. I gave him my URL and mentioned to him that there were several others and gave him this URL too (to the ZC Forums) and he is researching the problem and is *supposed* to call me back. We'll see. I'll post if I get any updates

I would love to hear what they say to you. They told me nothing was wrong and that I needed to upgrade to Website Payment Pro. They had no answers for why it worked with Website Payment Standard one moment and then didn't the next.

i am having the same error message... which i only found out about when customers started emailing me about it. it worked fine for weeks, with the odd error that i attributed to user error. i encouraged people to checkout with check/m.o module and then send paypal afterward; i adjusted their orders manually.

meanwhile, PP express orders slowly decreased, but were still trickling through up until yesterday. today, all orders are coming in under paypal IPN, along with a few emails from people describing the error. (luckily i never deleted the IPN module. i use paypal for all transactions, and since the express module requires a paypal account, i kept IPN for CC customers w/out paypal accounts)

IPN continues to work fine.

I called my hosting company to make sure that they hadn't done any upgrades that would have caused problems. So it doesn't appear that it is from the hosting company.

I am not sure why it would have quit working when no changes have been made.

The only thing I have done on my site is add product since it last worked properly.

Same story here--everything was working. I couldn't make IPN work for echecks so I switched to paypal express. I used it would problems for a few days and then it suddenly stopped working. I've made no changes to the site-I've only added additional merchandise.
