Hello, I recovered access to my site because the error was from a plugin and it arose during the restoration of a failed backup, but none of the backups that I had in backupguard worked, so I deleted them all, That′s a pity! I cannot retrieve the log. I always saw that every few days some backup said “warning” but I ignored it and used others, the next time I see this notice I will download the log as you tell me and I will contact you again, for now my site is fine. Thank you very much for your kind answer!
