Did everything, but no change to HTTP

It’s been a month since I have been trying to fix this problem. I use SUMO share count plugin. To get the share counts back, I got support from SUMO with communication back and forth. No luck. He had to give up. He says this:

“I’ve tried modifying your .htaccess file a few times, but without any luck. ??

Whichever configuration I used, the OG tags still remained as https after fetching from Facebook.

As we don’t support that plugin, I would highly recommend reaching out to them and asking what exactly is not working out on your site and tell them you tried everything they suggested in the description.”

Could you please help me?
