Another error which is coming for the following URL: https://gateoverflow.in/141764/do-we-need-to-study-the-proof-of-master-theorem-for-gate

I guess, it is coming for questions without Best Answer being selected.

I don't get that error when I test the page here: https://search.google.com/structured-data/testing-tool/u/0/#url=https%3A%2F%2Fgateoverflow.in%2F141764%2Fdo-we-need-to-study-the-proof-of-master-theorem-for-gate

If you're still getting the problem you should check your theme customisations against qa-theme-base.php, some places have new tags output, e.g. https://github.com/q2a/question2answer/blob/bugfix/qa-include/qa-theme-base.php#L2297

Thanks Scott. I might have overridden those functions. Will check.
