JSONObject error

I have an error that is showing up when running my start.bat file

JSONObject [“sitemap”] not a string

is coming up, and keeps on appearing when I change anything on my running platfom.

I am also seeing this error when I have NetworkHealth items in my sitemap.
Not when OH starts but when using the web interface

2016-06-19 21:04:14.942 [ERROR] [.myopenhab.internal.MyOHClient] - JSONObject["sitemap"] not a string.

Any suggestions?
