Bug: % not escaped in printf if using PHP 8.x

Hi there,

I ran into issues with this plugin using WordPress 6.0.1 and PHP 8.x (8.0, 8.1, …):

file: /wp-content/plugins/creative-commons/includes/class-creativecommons.php
line: 927
issue: in the CSS, there is a “20%;”. It seems that printf starting from PHP 8.0 cannot parse it.
solution: It needs to be escaped like “20%%;”.

Cheers,
Janek
