keep seeing js errors in browser console for a portal integrated site

HI

 

 

We have configured a new site for a client

 

 

After they created a simple set of layers and added them to a site, the browser shows a number of errors related to js syntax errors

 

 

This occurs with all 3 major browsers.

 

 

The viewer seems to load OK, just has these errors which I cant resolve

 

 

 

Error: Syntax error Error: Syntax error

All of the usual post install configuration has been done to federate with portal

 

 

Anyone had this before?
