Dúvida no Wordpress


walmir57

Pergunta

Bom dia pessoal,

 

Sou novo por aqui e descobri essa mina de ouro que é este Fórum e preciso de ajuda dos amigos.

Tenho um site em Wordpress e recentemente apareceu uma linha de texto no topo da página com os seguintes dizeres:

Warning: trim() expects parameter 1 to be string, array given in /home/sommaise/public_html/wp-includes/shortcodes.php on line 92

Abri o arquivo shortcodes.php no Dreamweaver e lá está assim:

    if ( '' == trim( $tag ) ) {
        $message = __( 'Invalid shortcode name: Empty name given.' );
        _doing_it_wrong( __FUNCTION__, $message, '4.4.0' );
        return;
    }

 

Alguém poderia me ajudar a corrigir isso?

Fiz um Upload de todo Wordpress menos a pasta wp-content mas não deu certo.

Também não estou conseguindo fazer o login pelo wp-admin dá erro. http://www.sommaiseu.org.br/wp-admin

Só tenho acesso pelo CPANEL e consequentemente ao gerenciador de arquivos ou FTP - FILEZILA.

Não como ou o que alterar no código da página que é indicada como contendo o erro. Será que o caminho é este??

 

Segue o código integral do arquivo  Warning: trim() expects parameter 1 to be string, array given in /home/sommaise/public_html/wp-includes/shortcodes.php on line 92

/**
 * WordPress API for creating bbcode like tags or what WordPress calls
 * "shortcodes." The tag and attribute parsing or regular expression code is
 * based on the Textpattern tag parser.
 *
 * A few examples are below:
 *
 * [shortcode /]
 * [shortcode foo="bar" baz="bing" /]
 * [shortcode foo="bar"]content[/shortcode]
 *
 * Shortcode tags support attributes and enclosed content, but does not entirely
 * support inline shortcodes in other shortcodes. You will have to call the
 * shortcode parser in your function to account for that.
