Error messages with version 1.09

[gingi101]

I've just installed One Page checkout for the first time (version 1.09).

When I installed it on my laptop in my local development site everything worked well.

However, when I installed it on my real website (hosted at fatcow.com) I get errors for any operation I'm doing in the checkout process.

Basically, for every operation I get a message box with the following error:

There was an error updating shopping cart, please inform IT Web Experts about this error.

or

There was an error updating your billing address, please inform IT Web Experts about this error.

or other versions of that error.

I get it for every field that I update in the form.

In addition, the sign near the e-mail field stays red and doesn't turn to green.

 

Any ideas?

 

Thanks,

David
