What can cause this error?

Answer 1

System -> System Settings.
There will be a long list of parameters. One of the parameter groups is responsible for opening the gallery. You can recognize this parameter by the value of the path that is written in the error.
It needs to be forwarded to match the new site location, or the path needs to be simplified so that it doesn't depend on the domain.
You'll probably see more settings tied to the old domain, so you'll need to look at all the settings.
