Onepage checkout fails billing step after 1.9.4 upgrade

Onepage checkout fails billing step after 1.9.4 upgrade

I upgraded an older 1.9.2 CEO site to 1.9.4. Regardless of theme, an older rocket theme, rwd and default all give the same problem. Continuing from billing info redirects to cart. Isolated to a 500 error in saveBilling. I encountered the same error a couple of years ago but can’t recall the solution. Note form key is turned off but shouldn’t be an issue as the RT them doesn’t overide default onepage checkout.

Re: Onepage checkout fails billing step after 1.9.4 upgrade

Hi a 500 error is a general internal server error message telling that the server could not process the request.

 

Please provide some more information.

 

Do you have a php error_log ?
Also does exception and system.log in /var/log provides any useful information ?

Re: Onepage checkout fails billing step after 1.9.4 upgrade

I enable developer mode in index.php and nada in exception, system or php error logs. However when enabled jscript console shows nothing and continue stays on billing section rather than redirect to cart. When developer is not set jscript consoel gives ...

 

[Error] Failed to load resource: the server responded with a status of 500 (Internal Server Error) (saveBilling, line 0)

 

Further debugging in devtools..

 

Shows  POST mydomain/checkout/onepage/saveBilling/ 500 error  in prototype.js:1530.. 

 

Billing.phtml sets up that url as the on click on continue from the billing step. 

 

At this ;point my jscript skills run out and and I can't work out why the saveBilling url is being setup. 

Re: Onepage checkout fails billing step after 1.9.4 upgrade

May I ask what kind of payment provider you have enabled?

 

This error has been related to some payment methods like Amaszon, and alos earlier year it was a conflict with Supee-7405 etc.

 

What Magento Version did you upgrade from ? You have upgraded one version at the time (not missing any one) could be there is something not upgraded right. Please advice.

Re: Onepage checkout fails billing step after 1.9.4 upgrade

Paypal. and express is working fine i.e when the checkout steps are bypassed.

 

The upgrade was CE1.9.2.4 to 1.9.4 . The symptoms certainly "smell" like a  bad upgrade. So unless i get another idea I am going to downgrade back to 1.9.2 and bring forward in smaller steps. 

 

 

Re: Onepage checkout fails billing step after 1.9.4 upgrade

I downgraded to 1.9.3.3 and all works as  expected.. so something in the upgrades broke. Il bring the site forward in baby steps and see where the culprit is. 

Re: Onepage checkout fails billing step after 1.9.4 upgrade

Re: Onepage checkout fails billing step after 1.9.4 upgrade

I am also getting the same issue with PayPal Plus module.
