I made the website on a temp URL, as usual. I ran into a problem and had to bring back a backup. It didn't work, but I found in your docs that restoring to a temp URL doesn't work. Not yet ready to go live, but needing to finish, I bought another domain, set it up on my server and restored without issue.
I was ready to transfer to live and tried to restore on the client's URL which is on the same server. Same ajax error.
I made a backup of the original site on my client's URL and tried to restore that until I could figure this out and I get the same error trying to restore that.
I've had to temporarily redirect my client's URL to the new one. This won't work for long and I shouldn't have to use this type of workaround.
Please advise.
