How to the error message display on in case of unexpected blank pages?

In prestashop  back-office and/or front-office start displaying a blank page  or incomplete page regularly without any error message, it is necessary to activate the display of the PHP errors in order to understand the problem.
This is done in your PrestaShop installation's /config/defines.inc.php file. You should edit the following line:
define('_PS_MODE_DEV_', false);
...and change it into:
define('_PS_MODE_DEV_', true);
Now browse your store's pages again. PrestaShop will display all the relevant error messages (if any), which should help you solve the issue.
Once the issue has been fixed, you must revert your changes: edit the /config/defines.inc.php file again and put false back as the value for the_PS_MODE_DEV_ constant.
