Hi,
My host provider just block my website (Forbidden You don't have permission to access / on this server.) and sent me an hacking alert with this message :
Executing deleted program
Commande apparente : ././crond
Exécutable utilisé : www/wp-content/plugins/easy-columns/img/.nfs0000000004824a2100001b9a
Does it means the issue come from your plugin ?
Thank you for your help.
