Lines: 64, 65, 66

 

<?php }

• Versiune PHP7.3.25
• Versiune MySQL5.7

 

Unde este incorect?

 

Multumesc anticipat

wp_head e o functie https://developer.wordpress.org/reference/functions/wp_head/. Incearca wp_head() pe linia 65 in loc de wp_head.

[Wav3]

add_action( string $tag, callable $function_to_add, int $priority = 10, int $accepted_args = 1 )

Deci probabil trebuie pus intre ghilimele, nu callable (adica nu cu ()). Give it a try, dar n-o lua de buna ca nu stiu WP.
