og:image still appearing after removing from theme

I’ve followed the instructions here and removed the code indicated: https://www.screencast.com/t/nTde1SGwJid.

However, I’m still seeing the og:image added. I’ve been through the documentation and forums here and it seems like removing this code should do the trick, but that extra line with og:image still appears. Is there another way to troubleshoot this? I’ve removed from my main and the child theme and from mobile just in case.

I’m getting two errors related to the td_wp_booster_functions.php

PHP Fatal error: Uncaught Error: Call to undefined function do_action() in /nas/content/live/rtchronicles/wp-content/themes/Newspaper-Child/includes/wp_booster/td_wp_booster_functions.php:8\nStack trace:\n#0 {main}\n thrown in /nas/content/live/rtchronicles/wp-content/themes/Newspaper-Child/includes/wp_booster/td_wp_booster_functions.php on line 8

Line 8 is: do_action(‘td_wp_booster_before’); //@todo is probably not used by anyone

Upon further review…the above error is completely unrelated.

I’ve tried to edit the includes/wp_booster/td_wp_booster_functions.php file in both the WP editor and via SFPT for both my child and parent. Both have the line in the instructions you supplied commented out, but the og:image line still shows on my site. I also found that no changes I make to that file actually get rendered on my site. I have worked with a ton of people on my end to ensure this isn’t a cache issue, so the only thing left is an issue with the theme.
