I have a standard SharePoint 2013 Teamsite template with "seattle" masterpage and added jquery in the head of the seattle.html to solve some branding issues(screen 1). The problem is that I always get a javascript error from my browser (screen 2). I tried different things but with no luck, e.g. change the position of the scriptlink tag; I tried to choose different jquery versions (2.1.0, 1.11.0, 1.10.1); I recreated the website. The strange thing is that I don't have any problem with other templates (searchcenter, documentcenter). This behavior only exists with the teamsite template. Would be nice if anybody has an idea to solve this. If you miss some information please ask for them. Thank you!
