Ela,
I just reread your msg, and see that you recently updated. Assuming that you are referring to updating to the newest version of WP, that is probably the problem. The new wp may not be compatible with the Updraftplus software. If this is the case, contact your web host to see if they have a recent copy of your site saved (many do this for their customers, but may not advertise this), and if so, ask them to re-install the previous WP software. That may well take care of your banner and the updraft plus restoration issues. If they do not have a version, ask them if there is any way to see how far the updraft plus software got before it crashed. In my case, it had not changed any files yet, so when the replaced the WP with the older version, all of my problems (slider, stripe payments) that were not working started working again, and I did not even have to use their back up.
As a rule, it is usually better to wait a little while before installing new versions of operating systems. It takes time for plug-in developers to discover and fix problems.
