turn off PrestaShop error reporting (should not be run in production unless debugging issue)

I think Prestashop error reporting is turned off. The URL is not in productin yet.

Do you want to say that in defines.inc.php I have to write: @ini_set('display_errors', 'off'); ??

this is why posting your ps version is a good idea.

 

to turn off error reporting review this link (as it's different depending on ps version)

Yes, I have done this before I wrote to you (I attach a capture).

Basically, my problem is that I can not access to my backend. The screen is blank although the shop (in frontend) is correct. http://xurl.es/esb1y

 

Can you help me?

did you transfer shop and/or modify any native prestashop core files?

I moved the directory of the shop because I started in another directory for test and now is real (actually in mantenaince). The front office is on but the problem is in the back office.

if you see errors/notifications from php engine even if the error reporting is turned on, i bet that one module from modules that you use has got code like @ini_set('display_errors', 'on'); 

 

try to disable non-native modules and check if this notification message appears

Thank you. I've done all things that you told me without exit. I'm trying to install again from the begining.

I'll keep you inform about it.
