Bom dia!
Estou tendo um problema, no qual, com alguns usuários, ao clicarem em mensagem aparece o erro (imagem abaixo):
Erro ao ler a base de dados
Arquivo: /lib/dml/moodle_database.php
Linha: 486
MySQL server has gone away
SELECT mdl_context.id AS ctxid, mdl_context.path AS ctxpath, mdl_context.depth AS ctxdepth, mdl_context.contextlevel AS ctxlevel, mdl_context.instanceid AS ctxinstance, mdl_context.locked AS ctxlocked FROM mdl_context WHERE id IN (?,?)
[array (
0 => NULL,
1 => NULL,
)]

E também, não conseguem visualizar as mensagens privadas.
Alguém tem ideia do que se trata?
