H1 Tag not working and links keep breaking

We have a spring web template on our website. It was working fine when it was on staging site but not that it has gone live, Nightwatch doesn’t seem to recognise the H1 tag we have in place and the links keep breaking. Also, some elements are not responding. Can someone help?

Thank you.

Can you please share website URL & credentials so i may look into the malfunctioning. Do share both (main website and also of the staging website)

About the links breaking will have to see the code. It might be conflicting with any plugin
