This is a Drual 6 site with internationalization enabled for CiviCRM. There are no extensions installed. Site was updated from 4.7.8 to 4.7.11.
After running the db update script, the System Status in the footer has remained "Critical", despite the only red flag prior to the update being that the site needed to be updated.
When visiting the System Status page, it no longer displays any setting statuses, including the usual greens for php version, etc.
After running the db update script for 4.7.11 there were no errors on the update screen - back on the dashboard, however, the widgets failed to load and there was a DB error, but refreshed the page and it went away (and widgets came back) and hasn't come back since. The logs showed the DB error was due to a timezone error (I can paste the log details if desired).
The timezone issue is not appearing in a pop-up as (like I've seen on other sites), it is unknown if the error is the cause of what's breaking the system status page as I have been ignoring the timezone issue since it's not critical. Either way, this does not explain why the system status is now displaying as critical.
Thanks for any suggestions!
Update: issues still present in 4.7.14
