After a failed WordPress auto update, this site was not accessible. Attempting to restore from the backend backup also failed with permission errors. One call to my ISP corrected the problem quickly and easily. The Online Backup I had been using decided to stop providing free support and discontinued their plugin a month prior to this, so that restore option was not a solution. This is just to advise you that your ISP does make daily, weekly, and monthly backups (depending on your ISP and subscription) that can resolve many issues. Call them when you need support, that is why they are there.
