Fresh install blank screen

Hello,
Moving my sites to a new hosting.
Installing software on a new domain.
If i go to install url i get a blank screen.
Any ideas?

First thing first, contact David to change your domain for your license and get the new license code for the config.php file. Then make sure your sql database login info is correct and data prefix is match. Or check php version, should be version 7. something

He did give me that new key, but im downloading a fresh zipfile under the new domain from the customer area. So i guess the license file should be correct.
Im using siteground now and the php is some new fast loading version they have. Will have to check that.

cannot find the problem here, flynax will need to help.tried changing php versions but no luck.
the domain is flippalot.com.

thanks.
