strange code warning at bottom of page

[alasdair17]

hey @arminunruh, i'm reworking a website just now and updated lay to activate overlays. The following errors started being displayed at the bottom of the page and on other pages the errors were longer and mentioned my custom id tags I had applied to certain elements. I've reverted to 5.9.6 which doesn't display the error.

Just a heads up.

The errors:

Warning: DOMDocument::loadHTML(): ID grid-css already defined in Entity, line: 49 in /home/customer/www/scapscotland.com/public_html/wp-content/themes/lay/frontend/assets/php/overlays/overlays.php on line 40

Warning: DOMDocument::loadHTML(): ID phone-grid-css already defined in Entity, line: 160 in /home/customer/www/scapscotland.com/public_html/wp-content/themes/lay/frontend/assets/php/overlays/overlays.php on line 40

Warning: DOMDocument::loadHTML(): Tag nav invalid in Entity, line: 219 in /home/customer/www/scapscotland.com/public_html/wp-content/themes/lay/frontend/assets/php/overlays/overlays.php on line 40

yea

its just a warning, not an error.
you need to disable wp_debug in your wp-config.php so the warning wont show up

define( 'WP_DEBUG', false );

basically im traversing the html of pages to find all links to overlays, so i only pre-load overlays that are linked to on the current page

because that html contains multiple elements of id "grid-css", that php shows a warning, because html is supposed to only have unique ids :D
