Guess you have an json error due to a facebook plugin. Deactivate it and see if it change something. If it is coming with your theme, see if an update is avaible or if something is related to this on your theme support.
Seems also that you modified your theme name. Doing this is not recommended as it the best way to introduce some errors because of missing files or wrong slugs. Specially when high js management is built in.
Test your install with 2015, and activate your theme only if anything is working correctly with this default setup.
