I have a problem on the magento ecommerce that I am creating. When I procede to checkout in the "billing information" section, the button "continue" after I insert user personal data doesn't work. It also doesn't work if I try to procede with a registered user.
Here is the link to the test website:
In the system.log file the following error appears:
2014-07-30T09:47:26+00:00 ERR (3): Warning: include(Mage/Eav/Model/Attribute/Data/.php) [function.include]: failed to open stream: No such file or directory in /lib/Varien/Autoload.php on line 93
2014-07-30T09:47:26+00:00 ERR (3): Warning: include() [function.include]: Failed opening 'Mage/Eav/Model/Attribute/Data/.php' for inclusion (include_path='/app/code/local:/app/code/community:/app/code/core:/lib:.:/usr/local/php53/pear') in /lib/Varien/Autoload.php on line 93
I tried researching a bit and as suggested by someone I already attempted replacing the Autoload.php file. The error persists though. The system requirements are met. I have magento 18.104.22.168. Anyone can help?
Thank you very much.
Edit 1: I uploaded a screen with the database result following Dave's comment.
Edit 2: I don't know if it's related to this problem but another error pops up in the error log.
