OK done another new install & from the install link to storefront I get a blank screen, change the template to classic green & loads fine, switch back & blank screen.

FYI

ZC 1.5.5
PHP ver 5.6.15
MySQL 5.7.9
Apache 2.4.17

When using Chrome (my default browser) developers tab I do see issues, see attached image & guessing this is the reason for the problem?Click image for larger version.
