layout.js line 511

I'm not sure how I keep getting this. I updated the template bs3 to 2.1.6 & using plugin 2.3.1. I put custom code in the before header box. I don't know if that is the problem or something else. I can't save or save close. the layout option is gone as well because it won't load.

In admin I get jquery.min.js:4 and layout.js:511
