Field 'Database type' is required

Installing my Dolibarr
1

Im trying to install dolibarr on hostgator and it shows me these errors :

Field ‘Database type’ is required
Field ‘Server’ is required
Field ‘Database name’ is required
Field ‘Login’ is required

At the begin of installation it shows everything is ok :

Database Prerequisites check:
Ok PHP Version 5.6.30 (More information)
Ok This PHP supports variables POST and GET.
Ok This PHP supports sessions.
Ok This PHP support GD graphical functions.
Ok This PHP support Curl.
Ok This PHP support UTF8 functions.
Ok Your PHP max session memory is set to 256M. This should be enough.
Ok Configuration file htdocs/conf/conf.php exists.
Ok Configuration file htdocs/conf/conf.php is writable.

I suspect the problem is with the version of PHP ?

A little help please , thanks.

Update (SOLVED)

I was able to solve it by installing to another domain, i am using a shared host at HOSTGATOR, for some reasons it worked when i tried to install it to another domain because i have multiple domains in that host. By the testing i made it was not the version of php, or something related to technical requirement. I think it was a problem related to permissions.
