Trying to get Comments ON for Posts Pages

Hi there,

I want the Comments section to show at the bottom of each blog post. I’ve exhausted every solution in these forums for turning them on and they’re still not showing on my blog posts page: http://greenearthphotography.com/headshots-outdoors/

I’m using the Photolux theme.
What I’ve tried
*Discussion>Settings>Allow all comments. It’s checked.
*Photolux theme settings, comments are allowed for Pages (no option for Posts)
*Quick Edit of all posts, checked Allow Comments, which hadn’t been checked. I thought for SURE that was going to fix it. Nope.
*I use the Jetpack plugin for Shares, likes and comments. I tried deactivating all the plugins and reactivating one at a time. I disconnected from Jetpack and reconnected, deleted it and reinstalled.
*Checked with my host: SiteGround, they changed a few things that I had to change back, and still no comments section on my blog. Grrrr.
*I even ADDED CODE to my page.php and single.php (gasp). First I tried through my cPanel Public FTP before realizing I could go Appearance>Editor. When I did the latter, it the code I thought I added wasn’t actually there. So I did it again using code from another thread addressing this issue. It said to add <?php get_comments(); ?> right after
<?php get_content(); ?> on single/php. Mine doesn’t have <?php get_content(); ?> so I added it after //include the comments template
comments_template(); That didn’t do it. So I also added <?php get_content(); ?> too.
*Each time I’m emptying my cache and refreshing the page. No change.
*Then I added <?php get_content(); ?> <?php get_comments(); ?> on the page.php as well, just to see.
*I have post tags, and under the content on my post page, under Discussion, Allow Comments and Allow Trackbacks are both checked.
*I did a Live Preview using the 2015 theme, and the Comments section IS THERE.

What am I doing wrong? How can I get the comments to show? Please help. I worked on this ALL day yesterday. So disconcerting. Thank you!
