Can it be solved by simply setting define(‘WP_CACHE’,false); from my end?

I’m still not sure what’s the workaround for the ‘Notice: Undefined index: mode’ warning though.

Looks like the field_type has different values (I’m not sure where that came from), but it’s now fixed by changing them inside the switch operator line 718:

1 for ‘NGGCF_FIELD_TYPE_INPUT’
2 for ‘NGGCF_FIELD_TYPE_TEXTAREA’
3 for ‘NGGCF_FIELD_TYPE_SELECT’

Now I’m getting this error in line 721 for empty field value, and fixed using ternary operator as follows:

<?php echo !empty($value) ? esc_attr($value->field_value):''; ?>

The wpdb::escape warning is gone by replacing all $wpdb->escape to $wpdb->_escape in the plugin file. Now there’s another error in every custom field showing in the gallery images page:

Trying to get property of non-object in <b>/wp-content/plugins/nextgen-gallery-custom-fields/ngg-custom-fields.php</b> on line <b>720
