Erro nas linhas do post

Bom, estamos com um problema ao postar uma foto no blog.
Ao criar uma página de post, ele nos dá a opção de subirmos uma imagem como “imagem destacada”.
Subimos a imagem, na página do blog ela é exibida em 240x355px(tamanho padrão do wordpress), e ao abrir o link do post, a imagem aparece em tamanho real como realmente deve ser, porém abaixo do texto do post, aparecem as seguintes linhas de código com erro. E sem a imagem, o post aparece normal, como os outros que tem de exemplo no site.
