Some readers have problems leaving a comment

I’ve been using GoBlog since March 2015 and like it very much. But for some reason several months ago some of my readers started having problems leaving a comment. The WP comment box will let them write the comment but then suddenly won’t accept their name, email, and URL, so it can’t be posted. Using Chrome seems to be one of the problems. Just wondered if anybody else has this same issue. Is this WP, GoBlog, Chrome, a plugin or something else entirely.

Have you tried reaching out to the author of that theme? They may have seen something like that before, or there may be a theme update that fixes that. Here is their support information.
