Hi,
I've setup a site comprising
:: Apache 2.4 + mod_proxy_fcgi;
:: PHP-FPM 5.4;
:: MySQL 5.4;
:: Drupal 7.34.
I managed to carry out the Drupal setup, albeit not with the "regular" display, but instead with a white page, text only, stripped of every graphical element except the Drupal log.
Afterwards when browsing the site the same there: white page, text only, no graphical elements, themes, etc.
It appears as if any colour, images, background, javascript etc. has simply been ripped away.
