My programmer asks:
If they mean the original .htaccess file before adding their code, that is what is there now. I wonder if they want just a plain file without all the Wordfence stuff in it? That would be the only two things I can think of that they mean.

We asked a question at Theme Forest and you asked us to enter a ticket into your support system, which we did. After the update, many images were missing. You sent a support thread, we tried it (edited htaccess) and it didn’t work. We set the htaccess back to the original. You asked for a login to the site to fix it and we provided it in this ticket thread. Can you fix the site after the theme update?

We launched the site, which is why I waited to reply (it was on our dev server). I can turn on your login credentials if you want them.
PHP Version is 5.6.30 (on the hosting server, where the site is now.)
