I'm having issues with my server upgrades to (a) new platform and (b) webpagetest 3.0 and wondering if anybody has some clues/tips/ideas of what it is that I am missing...

Testing on 3 different machines, i see the following:

Server A
CentOS7, PHP 7.0.16, FPM/FastCGI, NGINX 1.10.2
Included /var/www/webpagetest/www/nginx.conf (for rewrite rules)
From /install page:
- Every single item is green
Running runtest.php:
- Undefined variable: req_domelement in /var/www/webpagetest/www/runtest.php on line 104
- error on line 2 at column 6: XML declaration allowed only at the start of the document
Also:
- Waterfall and thumbnail images not showing (showing spinner)

Server B
CentOS6, PHP 5.4.16, Apache 2.4.6
HTTP_MOD_REWRITE = On
From /install page:
- Every single item is green
Running runtest.php:
- Undefined variable: req_domelement in /var/www/webpagetest/www/runtest.php on line 104
Also:
- Waterfall and thumbnail images ARE working!

Server C
local machine, windows/WAMP: PHP 5.6.25, Apache 2.4.23
HTTP_MOD_REWRITE = On
From /install page:
- GD module installed
- all (non-optional) checks are green
- all file system checks OK
Running runtest.php:
- Undefined variable: req_domelement in C:\Users\mverkerk\dev\webpagetest\www\runtest.php on line 104
