 * I got an email saying “An error of type E_ERROR was caused in line 503 of the
   file /home3/plyvstmy/public_html/wp-content/plugins/responsive-lightbox/includes/
   class-frontend.php. Error message: Uncaught Error: Unsupported operand types 
   in /home3/plyvstmy/public_html/wp-content/plugins/responsive-lightbox/includes/
   class-frontend.php:503″
 * I have not experienced any issues on the site. Should I worry about this? I have
   no idea how to fix it or figure it out. I saw someone else had this same email
   in the forum, but no one replied to their inquiry.
