Failed opening required '_PS_CONFIG_DIR_autoload.php' ?

[4GLte.eu]

I cant load the front ena and back office. In dev mode I receive the error:

 

Notice: Use of undefined constant _PS_CONFIG_DIR_ - assumed '_PS_CONFIG_DIR_' in /home/aaaaaaa/domains/domain.com/public_html/config/config.inc.php on line 64

Does config/defines.inc.php exist on your server? If not, restore it from a backup or the original PrestaShop archive. If it does exist, make sure it contains the following line:

define('_PS_CONFIG_DIR_',             _PS_CORE_DIR_.'/config/');
