I will ask my host for some help with another ticket, since this is probably another problem on their end, maybe related to MYISAM.

my dev also did a fresh install early this morning in a /public_html/zen folder he made. He and I both had the same result with a blank page when accessing zc_install.

There are several empty databases sitting on the site, but does this matter in the sense that I can't even get to the first step of the install let alone the step where I'd be able to tell the installer to create a new DB or upgrade.
