Jonathan,
This usually happens if there were changes made to the server-side repository without HgLab knowing it. Were there any
rebases,stripor something of the kind?2 Posted by Jonathan Sato on 17 Jun, 2014 01:16 PM
Hi Anton,
I believe there was a recent strip performed on that repo. Do you have any suggestions on how to resolve the issue?
Thanks,
Jonathan

Sure, there's a way out.
Take a peek inside HgLab database and there will be a
PushlogEntryItemtable. From there, you'll need to delete all rows whereChangesetequals to the Changeset ID of the changesets that were stripped.If you need more assistance, I'm always available for a TeamViewer session.

Thanks Anton! That did the trick. After deleting the stripped changesets, the UI immediately started working again.
