The hoster I use is 'Neostrada', a local hosting company.
I've got wordpress, MODX, and codeigniter sites running. All without any installation problems.
Running php version 5.6
Only caveat I can think of is the fact I don't have a domainname linked yet. So currently I'm working with server-ip-address/~user . Can this cause any problems?
I am using the master.zip straight from the pw website, so yes the install.php files resides in the root dir. Also, the db exists and username/password are correct.
EDIT: wow such response, much quick and thank you guys for being so welcoming
