saguaros That makes sense that the JS error is not directly related. I did find the global.json file in templates/ja_impact/local/etc/ and manually put in the custom google code that I wanted in the section before the close of the head tag, and it works fine and shows up as it should on the front end of the site. It also shows up in the text field of the theme editor after manually editing the global.json file. So it seems that it is something else that is preventing the file from being written to when clicking the Save button from within the theme editor.
Any other thoughts of what to look at?
