Just tried to install 2.3.1 and it looks like the sapphire/dev/install/config-form.html is missing some php start tags. I made the following fixes and it works
now

line 62 & 63

<li>........checked="checked"<?}?> ><label for="EmptyTemplate">..........</li>

becomes:

<li>........checked="checked"<?php } ?> ><label for="EmptyTemplate">..........</li>

Hi all,

This will only cause an error if short_open_tags is set to off, which is how it slipped through the cracks. We have since added automated tests that will attempt to parse the files with short_open_tags both off and on, which will stop this error from getting into a release in the future.

The fix will be released in 2.3.2; in the meantime everyone suffering from this problem should use Aram's fix.

Thanks,
Sam

Thanks Aram, I've never setup a SS site before so to find a problem in the install file didn't fill me with a lot of confidence from the get go.
Also, Thanks Sam for explaining the problem and putting it into context.

I was worried for a second there that I was going to have as much trouble as I did setting up a typo3 site!

Sound like this is a great support forum already!
