I was experiencing the exact same problem.
I checked the httpd-error.log and found the culprit - the .htaccess file which is in the includes directory is cuasing problems.
For the time being, I renamed it and now everythig is loading as expected.
The error message looks like:
/usr/local/www/apache22/data/store/includes/.htaccess: order not allowed here, referer: http://172.20.1.41/
The .htaccess file itself has instructions on what needs to be done in httpd.conf fo it to operate as designed.
