If so, you can disable it so the error will not be displayed on your shop page: [https://wordpress.org/support/article/debugging-in-wordpress/](https://wordpress.org/support/article/debugging-in-wordpress/) * Hope that helps. * Thread Starter [amslps](https://wordpress.org/support/users/amslps/) * (@amslps) * [2 years, 11 months ago](https://wordpress.org/support/topic/continue-to-prompt-php-error/#post-16857941) * I had set the OpenGraph Thumbnail, but why the plugin still caused the fatal error, log from woocommerce log, * ```wp-block-code 2023-06-29T14:22:05+00:00 CRITICAL Uncaught TypeError: Cannot access offset of type string on string in /usr/share/nginx/wordpress/wp-content/plugins/seo-by-rank-math/includes/opengraph/class-image.php:522Stack trace: 0 /usr/share/nginx/wordpress/wp-content/plugins/seo-by-rank-math/includes/opengraph/class-image.php(497): RankMath\OpenGraph\Image->set_content_image() 1 /usr/share/nginx/wordpress/wp-content/plugins/seo-by-rank-math/includes/opengraph/class-image.php(321): RankMath\OpenGraph\Image->set_singular_image() 2 /usr/share/nginx/wordpress/wp-content/plugins/seo-by-rank-math/includes/opengraph/class-image.php(81): RankMath\OpenGraph\Image->set_images() 3 /usr/share/nginx/wordpress/wp-content/plugins/seo-by-rank-math/includes/opengraph/class-facebook.php(266): RankMath\OpenGraph\Image->__construct() 4 /usr/share/nginx/wordpress/wp-includes/class-wp-hook.php(308): RankMath\OpenGraph\Facebook->image() 5 /usr/share/nginx/wordpress/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters() 6 /usr/share/nginx/wordpress/wp-includes/plugin.php(565): WP_Hook->do_action() 7 /usr/share/nginx/wordpress/wp-content/plugins/seo-by-rank-math/includes/traits/class-hooker.php(88): do_action_ref_array() 8 /usr/share/nginx/wordpress/wp-content/plugins/seo-by-rank-math/includes/opengraph/class-opengraph.php(74): RankMath\OpenGraph\OpenGraph->do_action() 9 /usr/share/nginx/wordpress/wp-includes/class-wp-hook.php(308): RankMath\OpenGraph\OpenGraph->output_tags() 10 /usr/share/nginx/wordpress/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters() 11 /usr/share/nginx/wordpress/wp-includes/plugin.php(565): WP_Hook->do_action() 12 /usr/share/nginx/wordpress/wp-content/plugins/seo-by-rank-math/includes/traits/class-hooker.php(88): do_action_ref_array() 13 /usr/share/nginx/wordpress/wp-content/plugins/seo-by-rank-math/includes/frontend/class-head.php(157): RankMath\Frontend\Head->do_action() 14 /usr/share/nginx/wordpress/wp-includes/class-wp-hook.php(308): RankMath\Frontend\Head->head() 15 /usr/share/nginx/wordpress/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters() 16 /usr/share/nginx/wordpress/wp-includes/plugin.php(517): WP_Hook->do_action() 17 /usr/share/nginx/wordpress/wp-includes/general-template.php(3043): do_action() 18 /usr/share/nginx/wordpress/wp-content/themes/Astra-Child-Theme/header.php(26): wp_head() 19 /usr/share/nginx/wordpress/wp-includes/template.php(783): require_once('…') 20 /usr/share/nginx/wordpress/wp-includes/template.php(718): load_template() 21 /usr/share/nginx/wordpress/wp-includes/general-template.php(48): locate_template() 22 /usr/share/nginx/wordpress/wp-content/themes/astra/page.php(20): get_header() 23 /usr/share/nginx/wordpress/wp-includes/template-loader.php(106): include('…') 24 /usr/share/nginx/wordpress/wp-blog-header.php(19): require_once('…') 25 /usr/share/nginx/wordpress/index.php(17): require('…') 26 {main} thrown in /usr/share/nginx/wordpress/wp-content/plugins/seo-by-rank-math/includes/opengraph/class-image.php on line 522 ``` * Plugin Support [Rank Math Support](https://wordpress.org/support/users/rankmathteam/) * (@rankmathteam) * [2 years, 11 months ago](https://wordpress.org/support/topic/continue-to-prompt-php-error/#post-16860061) * Hello [@amslps](https://wordpress.org/support/users/amslps/), * Can you please confirm if the error is logged on visiting a specific page or is present site-wide? You can enable the debug display in your wp-config.php file to figure that out. If the error is present on a specific page, then please change the featured image/social image to fix the issue as the error happens when the selected image has incorrect or missing info. * If the issue is present site-wide, please change the default OpenGraph thumbnail, and the issue should be resolved after that. * Let us know how that goes. Looking forward to helping you.
