Error Code for ‘Vantage_CircleIcon_Widget’

I’ve used Vantage premium theme and I’ve used well. But, now my website is no seen on mobile. Instead front page is appeared, error message is seen.
The error message is – Vantage_CircleIcon_Widget is not found in “xxx/xxx/xxx/wp-contents/plugin/wr-pagebuilder/core/helper/shortcode.php” on line 1096.
I found the ‘shortcode.php’, andI looked the line 1096. But I don’t know why.

Suddenly that error is occured so, I’am very embarrassed.

I wanna know solution.
Thanks.
