Magento one page checkout keeps redirecting back to the shopping cart

A few friends of mine run a Magento webshop (1.3) and they had the problem that customers would be redirected back to the shopping cart after filling in their personal information.

I tried the same, but my order would go through. I was kind of lost, why did it always work for me but it wouldn’t for other customers?

After some hours of searching I tried to enter my Gmail address instead of my personal address and that failed. I got redirected back as well.

A report showed up in var/report with a warning from the Zend Framework core saying that the gmail address could not be validated.

Some Googling brought me to the magento forums.

The bug is indeed in lib/Zend/Validate/Hostname.php on line 329


if (Zend_Loader::isReadable($classFile)) { 


if (file_exists($classFile) && Zend_Loader::isReadable($classFile)) { 

And you should be up and running again!

I haven’t debugged this further to find out what the root cause is, but I’d thought I’d share my solution.

My first post

This is just another personal blog on the big, big, big internet! I work as CTO at PCextreme B.V. and i will be posting a lot about my daily work.

Just like any other system administrator i run into problems i have to fix or some really undocumented software. Just like all other sysadmins i get a lot of information from various blogposts, so i thought, why not help other people by posting my information?

I’ll try to post as much as i can in english, but sometimes when the post is for dutch people only, i’ll make a post in dutch.

But most of my posts will be about Ubuntu Linux, KVM (Kernel Virtual Machine), iSCSI, DRBD, Apache, etc, etc. I’ll not try to post any information that can be found in a howto or documentation.

I hope i’ll be able to help some sysadmins in trouble!
