I am using a premium blogger template. It already has sigma.org setup. And can't understand how to edit & Fix structure data error problem.
Please take a look at my site www.sharetrick.com and if you guys know how to fix this, then please tell me as soon as possible.
I read related article before, but those can't help me to fix that problem. in my theme setup many places sigma.org are used that's why I'm getting confused.
