Ugh that is really unfortunate. There is a small amount of webhosts that have this problem. And except for your case I have only heard of one other case where the webhost was unable to do the configuration.
The urls that don't work, those are standard wordpress urls for getting data for your website. It's not something that I did myself.
I can give you a refund, just write an email to info@laytheme.com
Otherwise you could choose one of the hosts I recommend on
