This bug also affects version 8.20.10

Hello. It appears that option #2 hides the Jira help menu - thank you, Joe Bond - but we still have the Service Management menu. Here's what I have to hide all three help links, for JSW, JSM, and Core. Please help me improve my code; I am no CSS/HTML expert, but this works:

<style>
div#system-help-menu-content a#gh_view_help {display:none !important }
div#system-help-menu-content a#service-desk-view-help {display:none !important }
div#system-help-menu-content a#view_core_help {display:none !important }
</style>

Our Jira instance is up for more than 2,5 months and we get this error. However, our test instance was up for more than one month and the error did not occur there.

Meanwhile we did another reboot 1 week ago and the link is working again. Either a JIRA-instance "forgets" the correct link when running without a restart for a while or this was fixed by Atlassian in the meantime. Either one would be good to know.

It's funny: We updated to JIRA Software 7.9.0 on 18.05.2018. Immediately after the update the link to the JIRA Software Help worked again which is why I removed the script-thingy from the announcement banner to suppress the faulty link:

<style>
div#system-help-menu-content a#gh_view_help {display:none !important }
</style>

Now, a month later, the link is suddenly broken again and I receive the error message as stated above in the description. How can that be? The link, of course, breaks everywhere help is offered, like in Kanban Boards and the Control Chart in the Kanban Board-Reports (https://docs.atlassian.com/jira/$%7Bsoftware.help.space%7D/Control+Chart). The help-links to JIRA Core (https://docs.atlassian.com/jira/jcore-docs-079/) and JIRA Administration (https://docs.atlassian.com/jira/jadm-docs-079/) still get me to the online-help successfully. Does this happen every time online-help for a new JIRA Software version is released? Did the Jira Software documentation for version 7.10.0 break the online-help for all preceeding versions? We did not install further JIRA Software-updates since 18.05. and only slightly customized some email-templates (added the event type to the subject) - nothing that should break the link to the online-help on our side. We did update JIRA add-ons and UPM.

This is very annoying because I can remove the link from the official help-menu with the short snippet in the Announcement Banner, but this will not fix the link in the context-help of Kanban Boards etc.

We have the same issue with JIRA 7.3.1. We get a 404-error when we try to access the URL with this error-page:

404 Not Found

    Code: NoSuchKey
    Message: The specified key does not exist.
    Key: software/jira/docs/api/${software.help.space}/index.html

    HostId: ...

An Error Occurred While Attempting to Retrieve a Custom Error Document

    Code: NoSuchKey
    Message: The specified key does not exist.
    Key: error.html

Please fix this.

Hi, this is also happening in v 7.6.1, and with links like "What is a Kanban backlog?":
