Sua duvida não tem nenhuma relação com o objetivo do topico que é sobre atualização de versão. Por favor abra um novo topico, seguindo as regras de postagem sobre como adicionar esse addon ao seu phpBB3.Nelly Pimentel escreveu:Vinny, meu forum atualmente está no Forumeiros, por enquanto,pois vou desativá-lo. Instalei o PhpBB3 em localhost para testar, coloquei o estilo MW2 e o que não sei como fazer é exatamente como colocar o Iframe para hospedagem das imagens e preciso muito disso, pois meu usuários já se habituaram a usar. No forumeiros não tem atualização e tanbém não tenho acesso ao Banco de Dados.
Obrigada
Eu fiz os backups antes de subir os arquivos de atualização automáticos como você recomendou.Stealth360, antes de iniciar a atualização, faça uma copia de todos os arquivos e um backup do banco de dados. Por favor, poste um print de como é essa tela a qual você se refere.
