My Backlog and sprints have recently disappeared from my project view. Tried following articles like this one: https://community.atlassian.com/t5/Jira-questions/Backlog-Does-Not-Appear-on-Scrum-Board/qaq-p/258608, but I can't change anything that looks like its core Jira, all the modules say: {{Module cannot be modified}}. No other options listed for the plugin.
Community moderators have prevented the ability to post new answers.
This sounds like you have had your Jira Software access removed, (but not your Jira Core).
Do you have a "boards" item in your menu? Can you check your access rights?
