Posta todos os arquivos que são mencionados no erro...

 

 

2.3 - Use títulos e ícones adequados:
Ao criar um novo tópico no fórum, dê a ele um título que esteja relacionado ao conteúdo do tópico. Títulos como "Ajudaaa!" ou "Entrem aqui!" só pioram as coisas: ninguém vai saber do que se trata, e menos pessoas irão entrar para olhar o que você postou e também evite de usar o CAPSLOCK ao criar seu título.

 

mudarei.

Se quiser sua dúvida tirada, mande PM com os links, e não com a dúvida (outros podem ter a mesma dúvida, e o fórum serve para ser usado).
