Thank you, I appreciate your rapid response.
I have adjusted the height again and you should be able to see the bug.
That might because I have manually added a style to limit the TOC’s size.
You can adjust you Explorer window smaller (Less height for the site) and do that again, you will see the problem.
Even under the current situation, you can see a large gap, but not lined up with the section on the left, but they shared the same margin attribute.
I have checked the UpdraftPlus again, when username and password entered, it appears that the Backup Order was sent, and the backup was started, but the mothership says error 61.
