Can Not Turning The Error Message Display On

[travv tree]

Hi,

 

i try to progress a new module but stuck in a step which lead me to a blank page.

i found out the way to open the error message display:

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);

 

i already change this 'false' into 'true', but not knowing why i still be lead to a blank page not show any error message.

 

How could i fix this problem?

 

 

Thanks

You have done it right, but some errors still don't show in Debug mode.
