PrestaShop max execution time installation of 50 seconds

[Decmin]

Hello,

I am trying to install Prestashop in One.com. I have tried with versions 1.7.6.2 and 1.7.6.1.

 

After launching the installation, in the last step I get this error message at 67%:

1: HTTP 503 - error -

 

After looking it up on Internet without interesting results, I have contact with One.com support and they have told me to enable PHP error messages and Prestashop debugging. Then, I get this new error message at 12% of the installation:

1: Warning: set_time_limit(): Cannot set max execution time limit due to system policy

 

They have also told me to do this:

In file /classes/ConfigurationTest.php > search for the function public static function test_dir > add at the beginning of this function these lines:

if ($recursive)
return true;

 

 

I get the same time warning message, and another advisor has told me that One.com has a limit, so I need a PrestaShop version with a maximum execution time installation of 50 seconds.

Could you help me, please?
