problem after successful Paypal

I'm sorry if this seems basic, but I am learning DW and ecart at the same time and...

I can successfully process cc transaction through my paypal pro account, money shows up on paypal and email receipt goes out perfectly but when you click checkout on confirm.php page it comes right back to that page after posting money on paypal with a bunch of these:
Warning: Division by zero in confirm.php on line 402

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at confirm.php on line 432

Warning: session_start() [function.session-start]: Cannot send session cache limiter -

Does this mean Paypal is returning back to the wrong page, should be checkout_success.php, if so where do I go to fix that? (without totally screwing up 3 days of work) Thanks any help appreciated.

I followed all the tutorial and guides step by step double checking every entry. Everything works except the last bit. After the final checkout step the cart goes to paypal processes the cc and credits my account, sends the email receipt but when it returns back to my site it loads the confirm.php page with a bunch of errors, it should go to checkout_success.php and show customer their receipt.

All connections are https and my certificate is not shared. Something is jacked with ecart, it is certainly not as easy as shown in the webassist demo video. I have not touched any of the code manually, I just followed the wizards step by step.

If anyone has any input it would be greatly appreciated as I need to get this working asap.

Thanks in advance.

You buy a webassist subscription based on a video demo that you can add shopping cart to your site and customize. Then you follow step by step guides and cart doesn't work. So, then you click on support and it takes you to this forum where apparently no support person reads or cares to respond. If you are not going to support your product then you should be honest about that up front, as paying customers expect the product their buying to work and when it doesn't then the expect support to make it right or a full refund. But, if you buy the subscription it's non refundable, so you end up with a product that doesn't work, no support and you can't get your money back. This all seems very dishonest to me. And after reading and searching the forum for days I see a lot of dissatisfied customers who were sold products that don't function as advertised.

I expect help with my issue or my money back.

I understand you are having a problem with your checkout and I would like to help you resolve it. The errors you are reporting with divide by 0 is not something that I have encountered myself on any eCart pages.

You can confirm that when you checkout with credit card that the transaction is occurring but instead of going to the checkout success page like you should you are getting this error on the confirm page rite? If so it seems that there might be a problem with one of the values that is being used on this page, probably around the line that the error is reporting.

To help you get this resolved I would like to see a copy of your confirm page that is causing this error. Please post back with this page in a zip archive minus the sensitive details like your PayPal login info and I will check it out to see if I can spot the problem quickly.

It also seems that you are unaware of the support hours and reply time policy, it is not that no one is here or cares, it is just that we work Mon-Fri 9-5 Pacific time. Your first post was made Friday afternoon and is being responded to on Monday morning, well within the stated support policy. This information can be found at the top of the forum under Hours and Policy.

Thanks for looking at code.

thanks for looking into this

I have looked at your page and I think I can see the problem. Currently in the UE code that is on lines 386-388 you have this:

$BurstSize = undefined;

$BurstTime = undefined;

$WaitTime = undefined;

You should update these lines so that they are like this instead:

$BurstSize = 200;

$BurstTime = 1;

$WaitTime = 1;

This should stop the error that you are getting when you get to this page. Please give this a try and let us know if it clears up the problem or if there are any other issues with this. I have logged this issue as a bug so that it can be fixed in a future update.

Thanks, problem solved, I apologize for my earlier rant, I was frustrated and I vented inappropriately. I appreciate your solving this issue for me.

No need to apologize, this is a bug in the software and we will work to resolve it, hopefully we can get a fix out for this soon for others.
