1) The native share buttons (the like & share button)
2) WP Socializer’s social icons (The one with red rounded count)
Native share buttons are deprecated and will be removed soon and if we still need to support it, then I have to provide you some code to change URL to http so that the count will appear. I suggest you to move to social icons alone as it is quick and clean.
For social icons count, both http and https count will be added so it is better to use it primarily. Please select “Load share count for both http and https URL of the page” under WP Socializer –> Settings –> COunter settings to yes and and the counter will be updated and cached in the selected frequency.
