I tried cloning an Sxa Site but it keeps on showing "Running Script" message and didn't get Success message at all. Is there any way to find out the progress/status of cloning.
Find this script in
/sitecore/system/Modules/PowerShell/Script Library/SXA/SXA - Site Manager/Functions/Run-SiteManager
end section and save it.
Once the cloning is finished you will see SiteManager window.
I tested it on SXA 1.8
and observer status of a job.
If you are using the newest version of SPE you should distinguish whether cloning is in progress or not by looking at the progress bar. When cloning is running progress will change status, otherwise, it will be green without any animation.
