Magento cart page is not showing

Question

My Magento cart page is not showing at all. It just comes up with a blank page. Previously this site was developed by another developer and He has disabled the Checkout process. Now I cannot find which settings he has done to stop the checkout process.

Can anyone tell me what are the possibilities to stop the default module from working.

Also every thing else is coming right on the cart page. Header and footer and all the things just that it is not rendering the html for cart block. The Content just came up empty, with no HTML.

Answer 1

Please open the adminpanel and then go to the

System/Configuration/Advanced 

there is a tab Disable Modules Output and then enable the Mage_checkout module

Answer 2

As I have told you the previous developer have disabled the modules. But that was not the case the developer have installed some extensions to disable the checkout process but that does not work very well. Then he tries to delete the extensions the wrong way so the entries that were made by those extensions was still in the database table "core_config_data".

And these values are being used by the left over files of the extensions ans he has overridden the magento core files for that. I just copy and replace the core magento files and also cleared the table "core_config_data" table and all things got working once again.
