fatal Error on the footer

I love the theme but recently after the update problems seem to be occurring anytime i do an upgrade. the theme was working fine but on waking up in the morning as i checked my website i saw this fatal error on the footer and some of the colors and widgets didn’t work. see below screen shots

Hello there,

I hope you are doing well today.

Could you please disable any third party plugins that you may have active currently as one of them may be causing a conflict here.

Also, would you be able to provide a link to the website so that it can be inspected?

Best Regards,
