I've the same problem. I've removed the cache folder of smarty but still blank page when trying to compare... Any other solution?

Thanks

turn on error reporting,

then instead of blank page you will see detailed information about what and where doesnt work (i hope so!)

 

open config/defines.inc.php

 

find this line: define('_PS_MODE_DEV_', false);

change to look like this: define('_PS_MODE_DEV_', true);

Thanks!! I didn't knew this option, very useful! I've got this message (This is a syntax error, I modified the % to have 2 decimals and I made an error):
