Hi David, thanks again….
Yes, I have followed all suggestions from the “Follow this link”….
1. When clicking “Back Up” now button, nothing happens, and the following error is presented: “Warning: WordPress has a number (4) of scheduled tasks which are overdue. Unless this is a development site, this probably means that the scheduler in your WordPress install is not working. Read this page for a guide to possible causes and how to fix it.”
2. Clicking the “Debug Full Backup” button appears to result in a successful backup, at least according to this logs.
3. It also appears that scheduled backups run with success. This is currently set to every 4 hrs….
