I recently update the PHP version on my site to 7.0. Now, when I go to my Revive adserver page at: https://datajaz.com/adserver, I'm getting this 503 error message: "Service Unavailable. The server is temporarily busy, try again later!" I then tried upgrading the Revive adserver version but couldn't complete the installation because of the 503 error. Not sure if it has anything to do with the PHP upgrade or not. Does anyone have any ideas? Thanks.
