Hi. I just asked this question in another thread, so I’m moving here to follow the news.
My site finally backed up after nearly an hour, but I’m unsure whether there are errors. I certainly see lots of time-out errors in the log.
There is an update available for the UpDraft plugin. I wonder if this is a fix for the problem. At the moment, I am hesitant to mess with it until I know if this has been resolved!
