Pourriez-vous m’indiquer de quoi il s’agit ?

[goldyfruit]

As-tu fait une mise à jour d’Apache (dépôt security) ?
Essaye de faire un test de la mémoire vive via la console Dedibox.

[Dr4gOoN]

ah ben un
#apt-get updaoe / upgrade
m’en a appris de belle, mon apache semblait ne pas etre a jour, je vais voir l’evolution, mais tout semble normal

Merci !
