The warning is regarding the following part of your code: __( )
.
In WP __
is actually a function for translation purposes.
From a short look in the manual, we can see that the __()
function usage is:
<?php $translated_text = __( $text, $domain ); ?>
And that the $text
parameter is required.
$text (string) (required) Text to translate. Default: None $domain
(string) (optional) Domain to retrieve the translated text. Default:
‘default’
In your code, you don’t send any argument to that function and therefore you’re getting a legit warning. To be honest, I don’t know why there was no argument in the first place. Moreover, also your remote server should show that warning. In case it doesn’t – or the code is different or you have error_reporting(0)
somewhere on the server (php.ini / wp-config.php).
A simple solution would be just to add an empty string as an argument.
