Not able to any items under navigation in Service Desk projects like Queue, Request Types, Reports..

[RG]

When we restart Jira service, We are not able to see any Service Desk features such as SLAs, Queues, Reports, Request Types....

But we re-index whole Jira system, We are able to see all features but getting popup error message, while assigning tickets, adding components, tagging users in comment.

• Is this happening while you fill the value of the assignee? ---->   yes. Every time you type a letter the error "jira was contacted but has return and error response"see picture that I have attached.
• is this happening to all users? ---> Yes.
• is this happening with all browsers --->  yess. we have IE and chrome.
• do you see any error?

Hi,

We have solved similar problem on our jira version 7.11.1 by doing these steps: 

• Implementing full synchronization of AD groups. We had incremental AD synchronization
• Re-indexing jira and Restarting Jira.
• Fixing Permission Scheme Errors which were in the log file. you can find them by running this query if you are using Oracle DB . (support team can provide you the insert query to solve this)

select * from project where ID not in (select source_node_id from nodeassociation where sink_node_entity='PermissionScheme')

• Removing 2 jira cache directories to force cache refresh. JIRA_HOME/plugins/.bundled-plugins and JIRA_HOME/plugins/.osgi-plugins ( of course Jira needs to be stopped)
• Added this parameter .(Jira Support team advised to do this)

. VM_SUPPORT_RECOMMENDED_ARGS="-Datlassian.darkfeature.com.atlassian.jira.application.active.users.count.cache.asynchronous=true 

• Removed and applied license again. Both jira and service Desk.

You should read the application log to find out what it is doing at the time of the errors. 

I'm slightly concerned by your "removed corrupt projects" though - what does that mean?
