Exception storing schema updates

Hello,

I’m new to this & just trying to set up a DreamFactory instance on a CentOS 7.1 server.

I’ve gone through the following installation guide:
https://github.com/dreamfactorysoftware/dsp-core/wiki/Install-CentOS-RedHat

The PHP timezone has been set to address the error in the log file below:
http://stackoverflow.com/questions/16765158/date-it-is-not-safe-to-rely-on-the-systems-timezone-settings

However, as soon as I enter the Administrator’s details on the DF start page, the error at the end occurs & the website is unusable.

Any ideas?

root@localhost log]# cat web.10.log

Are you having this same issue in DreamFactory 2.0 or is this an issue only on legacy versions?
