I have found the problem. There was an error in the grafity forms woocommerce plugin:
Fatal error: Call to undefined function wc_is_21x() in /public_html/wp-content/plugins/woocommerce-gravityforms-product-addons/gravityforms-product-addons.php on line 113
I've made a correction to that plugin code. I've added this line:
if ( !function_exists( "wc_is_21x" ) ) return;
to the wp-content/plugins/woocommerce-gravityforms-product-addons/gravityforms-product-addons.php line 113.
For even better performance, consider lowering the active plugins number below 15. The ajax search plugin finishes within 0.1 seconds based on the performance tracker results, the rest is system and other plugin initialization and execution time.Best,
