Hello,
Our site https://buttmullins.ie has been experiencing a critical error since Sunday.
I am getting the following info from WP_DEBUG:
Fatal error: Uncaught Error: Call to undefined function cornerstone_register_static_style() in /home/buttmull/public_html/wp-content/themes/x/framework/legacy/functions/frontend/styles.php:93 Stack trace: #0 /home/buttmull/public_html/wp-includes/class-wp-hook.php(308): x_output_generated_styles(’’) #1 /home/buttmull/public_html/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters(NULL, Array) #2 /home/buttmull/public_html/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #3 /home/buttmull/public_html/wp-includes/script-loader.php(2180): do_action(‘wp_enqueue_scri…’) #4 /home/buttmull/public_html/wp-includes/class-wp-hook.php(308): wp_enqueue_scripts(’’) #5 /home/buttmull/public_html/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters(NULL, Array) #6 /home/buttmull/public_html/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #7 /home/buttmull/public_html/wp-includes/general-template.php(3043): do_action(‘wp_head’) #8 /home/buttmull/public_html/wp-content/themes/x/framework/legacy/cranium/headers/ in /home/buttmull/public_html/wp-content/themes/x/framework/legacy/functions/frontend/styles.php on line 93
Can you please advise as to why this has happened and how to resolve the issue?
