I am not getting crucible review and neither the "create review" button of crucible.
Getting below error
WARN - Unable to find requested review: null, referer = null, request uri = [/cru/review.do]
WARN - Review with ID 3764 not found while getting Review by ID
Can you add here a snippet of the logs being written when trying to create the review in Crucible?
Which version of Crucible are you currently running?
I see that you commented on this question, in that case, the customer resolved the problem with a re-install of Crucible. Did you try that?
You may also want to raise a ticket with our support team (https://support.atlassian.com/contact) so that we can get access to the whole set of logs and required details.
Thanks, Caterina - Atlassian
