Blank page help. Prestashop 1.6


Recommended Posts

Hello, yesterday my site crashed.

I've now a blank page, and it's impossible to see why.

 

As i read in this forum, i've changed the defines.inc.php to see the errors. But the blank page is still here. Anyone can help me ? Many Thanks

{
    @ini_set('display_errors', 'on');
    @error_reporting(E_ALL | E_STRICT);
    define('_PS_DEBUG_SQL_', true);
}
else
{
    @ini_set('display_errors', 'off');
    define('_PS_DEBUG_SQL_', false);
}

Hello Vekia,

i reboot the mysql server this morning and the site is now accessible, I also clear the cache in Prestashop because Images didn't appear. I've the possible to upgrade the Ram memory on my hosting (256Mo : 10 €/month; 512Mo : 20€).

 

Do you think it's necessary to upgrade ?

Many thanks for you help.

Hi, the problem came on a prestashop 1.6 normal installation. (not after an upgrade with "1 click upgrade")

 

- after rebooting the mysql server, the website worked

- but the blank page came back after 1 day.

- we find in this forum this solution : "desactivate the expertise module in BO"

- today the blank page problem is solved.
