Call Query in php hangs other queries

Because when doing a first query to a call and then trying to make another one the php hangs? For example, running this simple stored procedure in php

DELIMITER $$
CREATE DEFINER='root'@'localhost' PROCEDURE 'curtidas_sp' (
    IN '@post' INT
)  
SELECT 
    COUNT(*) AS c_total,
FROM curtidas 
WHERE id_post = '@post'$$

DELIMITER ;

running in php:

$f_dados = mysqli_query($conexao, "CALL curtidas_sp('$idPost')");
$f_resultado = mysqli_fetch_assoc($f_dados);

And then try to run down another being a call or not

$c_dados = mysqli_query($conexao, "SELECT COUNT(*) AS f_total, FROM favoritos WHERE id_post = 2");
$c_resultado = mysqli_fetch_assoc($c_dados);

Displays this error:

mysqli_fetch_array () expects parameter 1 to be mysqli_result, boolean given ...
