I have this PHP Warning: Undefined array key “standard” in /public_html/wp-content/plugins/booster-plus-for-woocommerce/includes/shortcodes/class-wcj-orders-shortcodes.php on line 254\n
That line contains: $atts[‘standard’] = wcj_sanitize_input_attribute_values( $atts[‘standard’] );
The PHP warning, Undefined array key “standard”, occurs because the array key “standard” is not defined in the $atts array when it is being accessed. This can happen if the shortcode that the code is handling doesn’t include the standard attribute.
If you are able to modify the code then you can add the below line of code to the wp-config.php file. You can find this file directly to your domain. This will not display the errors on any pages.
Well, hiding errors does not solve the problem, does it?
I need to see errors from other plugins etc. too, just hiding errors is not an option.
Please solve the problem.
