Comments are redirecting to wrong URL after post

First, I’m seeing some references to the old site location, which is https://sharepointcandothat.com/blog, but the /blog should not be there.

I checked your Jetpack settings, and couldn’t find any references to your old site URL. If you still find references to /blog/, could you tell me where?

when users submit a comment, it’s redirecting to the following URL, which is giving a 404 error…

Your theme seems to be using a Javascript library to handle redirections and transitions between pages on your site. Could you try to switch to a different theme like Twenty Twelve for a few minutes, and check if the problem still occurs?

If that solves the issue, you will need to contact the theme author to let them know about this issue.

Thanks!
