After further investigation, it looks like it doesn’t like using YouTube ID
My temporary fix:
Go to the Social Count Settings and replace YouTube Username ID with your youtube username (e.g: mobilephone2003)
edit /wp-content/plugins/social-count-plus/includes/counters/class-social-count-plus-youtube-counter.php
On Line 52, replace
'%s?part=statistics&id=%s&key=%s',
with
'%s?part=statistics&forUsername=%s&key=%s',
Sorry, it still doesn’t work for me. Anything else to change than what you have mentioned?
@mobilephone2003 this need to be the channel ID.
I’ll change the plugin description.
@mobilephone2003 thanks for let know about it.
Version 3.1.1 fixed the option description: https://cloudup.com/ckpt2VkmmFo
