It gives a blank page after clicking "Buy Now" button in product listing page. Actually the product is added to the shopping cart but it returns a blank page. Does anyone know how to fix it? Thanks in advance!

Look at your PHP logs if you have access. If not enable errors via htaccess. Sounds like there is a PHP error on server.

or you can add this code to the page you are getting the error on

ini_set('display_errors',1); 
error_reporting(E_ALL);

It should force errors to show on the page.

That may or may not work depending on what and where the error is. If the error is on that script the ini will not work as the script will not execute.

Then again, it might work .... so was worth mentioning.

Tried to add the codes but blank page still came up and no error is displayed, sigh! Actually I notice that the "Buy Now" button sometimes work but sometimes doesn't. Would it related to the session issue?

Look at the code at the very top of the index.php in the root folder.

If it contains any of these php keywords:

base64_decode or gzinflate or eval

And you didn't put the code there then the page is hacked.

Oh yes, I found those php keywords not only in index.php but other php files as well. So my site got hacked. I need to upload the clean files again but how can I prevent it from happening again? Thanks!
