Pinterest feed not updating

Your plugin works great, except for the pinterest feed. I’ve checked the pinterest username to make sure it is spelled correctly, and when I click on the ‘Reload Pins’ button, I get redirected to a page with the following fatal error:

Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as XML' in /home/rapidslodge/public_html/wp-content/plugins/arscode-social-slider/arscode-social-slider.php:606 Stack trace: #0 /home/rapidslodge/public_html/wp-content/plugins/arscode-social-slider/arscode-social-slider.php(606): SimpleXMLElement->__construct('') #1 /home/rapidslodge/public_html/wp-content/plugins/arscode-social-slider/cron.php(5): fblb_getpifeed() #2 {main} thrown in /home/rapidslodge/public_html/wp-content/plugins/arscode-social-slider/arscode-social-slider.php on line 606

Because of this error, the pinterest posts haven’t updated for the past 6 months, so any help would be greatly appreciated!
