On multiple hosting platforms, every single time, without exception, upon which i have installed Concrete of any version (5.7 in this case) it has consistently failed to install the 'full-site' option. Whether the install was done manually or through some sort of 'fast install' option via the hosts control panel. Every single time an attempt was made to install the full site with theme and basic layout it has never been successful, ever.

Installing a blank site and then manually putting those elements into place has consistently been successful.

I can see this issue going as far back as what looks like 2011.
I got around it easily enough by just manually setting up the site from scratch but I have to ask;

What's the problem?

I seriously have not ever seen that option work on any platform under any circumstance under any amount of trouble shooting ever. Every single time I or someone else had to go in and make a manual change.

That said, once you get past that issue it is a pretty good CMS.
