New install shows blank pages after creating the admin user


#1

Hi All,
I tried installing Dreamfactory on ubuntu 12.04 from github using this guide: https://github.com/dreamfactorysoftware/dsp-core/wiki/Install-Debian-Ubuntu. The install completes fine and when I launch the site, I get a screen to create an admin user. I submit the form and after a few minutes I get a screen asking if I want free support. I click no and the screen seems to hang for a few more minutes, then I get a blank, all-white page after being redirected to “/dreamfactory/dist/index.html”. I am behind a proxy. Sounds like that matters.
Any help would be appreciated.
Thanks,
Leo

Where I’ve looked:

  • Apache error logs don’t show anything
  • Dreamfactory install log doesn’t show anything other than Apache restarting.
  • Dreamfactory error log shows what is below.

What’ I’ve tried

  • Installing on a brand new VM

  • Following the instructions here: Upgrading from 1.5.9 to 1.6.10 on AWS Bitnami (Several components do upgrade)

  • deleting the .registration file. Creating a new .registration file.

  • Navigating to /launchpad/index.html (I get a 500 error)

  • Restarting apache and mysql and rebooting the server

What version of PHP are you using?


#3

Well that was easy. I had an old version as the Ubuntu 12.04 repositories didn’t have the latest version. I upgraded to 5.6 thanks to Ondřej’s repository and it’s working.

Thanks!


#4

Glad my hunch was correct. We do depend on PHP 5.4 or higher.
