Posting answers causes Questions page to go blank

P.S. I’m looking at the page with Internet Explorer 8 (don’t know if it’s relevant).

Try going to Settings –> Permalinks and just hit save. I have had to do that in the past. Somehow it resets everything.

Thanks jeffmace, but that hasn’t fixed it for me.

Oh this fixes it. The theme was Twenty-fourteen. With a different theme the answers show OK. Thanks.

worked for me too
