I created a copy of the Seattle master page and added a javascript link to the new copy. Now that I have activated the new master page I receive "Something went wrong error" and I cannot get access to the site. Every attempt displays the previous error? Any ideas on how to get it back?
Other info:
- Created copy of master via Designer 2013
- Published new master page via Design Manager in SP I think I changed both the site AND admin master page to my new page (that's probably what broke it!)
- I can get to the top level site collection page
Thanks for your help!
