Thank you for reaching out and I am happy to help! I’ve checked your website and I do not see those errors in the console, however, I do see that the Minify currently is not enabled. Can you please share the screenshot of the Errors, and also the screenshot of the Performance>Minify section so I can check the settings? Are you experiencing any issue on the website regareding the performance?
Thank you for your feedback. So it seems that you are deferring minified JS both before </head> and after <body>. Can you please try to set those to Default (blocking) and see if the problem persists (Make sure to purge the cache after change) If the issue is gone, it means that some files need to be excluded from the process, like the /wp-content/plugins/w3-total-cache/pub/js/lazyload.min.js and the jQuery file.
Yes, the answer is because those files need to be eliminated as render blocking. This being said, If you deffered the files and the only issue is the console error while the website performance and usability is not impacted, you should keep doing it (previous state)
Alternatively, you need to exclude a specific file from being minified and deal with those files separately. Those console errors in the original report does not mean that there is anything wrong with the website
