It’s normal to see that notification in the console of your Webflow site, we added it to prevent Webflow users from potentially falling into a scam of somebody asking to paste malicious code there that could potentially give some scammers uninvited access to their Webflow account, but it’s just a standard warning for all Webflow projects.
However, that publishing issue you mention @ElviraNL sounds like odd behavior, did you receive a confirmation about your changes being published inside the Webflow Designer? I can see that your site was last published today.
