Memory limit issue Prestashop 1.6.1.1

[varovas]

Hi guys, 

 

I have an memory limit issue, and I cannot resolve it. What I have done:

 

1. Asked my hosting provider to make memory_limit to 256M.
2. Added "ini_set('memory_limit', '256M')" to config/config.inc.php.

3. Modified classes/Tools.php getMemoryLimit method by commenting "$memory_limit = @ini_get('memory_limit');" and added "$memory_limit = '256M'" instead. This made memory limit warning disappear. But then when I go to Catalog->Products, I get "Page could not be loaded" error;

 

Interesting fact, here's screen from Configuration information:

 

And this is screen from phpinfo():

 

Why memory limit is different in Configuration information?

Try adding ini_set('memory_limit', '-1') in config/config.inc.php and check if it helps.

It didn't help. Any other ideas?
