Problems after failed restore XML

[RCSLT Admin]

After failed attempt to restore using XML we are not able to reindex.

Obviously we can't be the only ones to have faced this so would be grateful for a reply on how to fix.  If possible how (step by step for a total moron) to restore JIRA using a database dump as the XML is not working.

After the failed restore, if I search for an issue from the project it appears but if I view the overview of the project, it will not show any issues.  I cannot move or clone them.

When trying to clone an issue:

Hi Navid,

I believe this is a duplicate case to https://community.atlassian.com/t5/Jira-Software-questions/Not-able-to-restore-system-or-perform-reindex-after-failed/qaq-p/765267

I don't want to duplicate our efforts, so I have replied about this issue on that other thread.

Please reply there instead.
