Cookie bar showing post id on the bar

You’d need to post the URL to your site for me to be able to say. Also, what did you add to the cookie bar message itself? It could possibly be you put something in there, maybe a shortcode? Did you edit the PHP? The code itself doesn’t touch anything to do with post/page IDs.

Another possibility is that another plugin is using jQuery to add content. You should disable all other plugins apart from cookie law info and test.

Hope that helps. For further info please see https://www.cookielawinfo.com
