Enfold Theme creating problems with SEO due to missing elements

Hi Guys,

Thanks for your continued support, but having run various SEO tests using well know tools, including Google Webmaster Tools, I keep getting SEO errors in the Enfold Theme which is giving my clients website a bad SEO score.

Only just 5 pages (and there are over 100 pages in the website) there are 251 errors, all flagging similar errors. Can you please shed some light on this please as I’m sure any feedback you can provide would be useful to other people using your fantastic theme.

Other errors include 404 pages shown in Google Webmaster Tools, such as;

wp-content/themes/lammore-consulting/js/dp.menu.js?ver=4.1.1
wp-content/themes/lammore-consulting/js/jquery.mCustomScrollbar.concat.min.js?ver=4.1.1
wp-content/themes/lammore-consulting/js/widgets/tabs.js?ver=4.1.1

This is a fantastic theme, but it would be great to have the SEO running as smoothly as the theme itself.
Thanks in advance,
