Purpose of this article
Jira automatically collapses comments by default when opening any Jira issue, forcing users to manually expands comments to see the entire discussion in the issue.
The parameter jira.comment.collapsing.minimum.hidden defines how many comments you need to have in addition to the baseline of 10 (minimum number of issues Jira will display before collapsing anything - not configurable; see JRASERVER-72359 - Create option for the number of visible comments).
If you have this parameter at 1 (default value on Jira 9+) this means Jira will not load the oldest comment when you have 11 comments.
Environment
Jira Server / Data Center on any version from 8.0.0
Resolution
The comment collapsing be disabled via either method listed below.
Method 1
Navigate to
Administration >> System >> General Configuration >> Advanced SettingsSet the jira.comment.collapsing.minimum.hidden parameter to 0
Method 2
Add the following line into your jira-config.properties file:
1jira.comment.collapsing.minimum.hidden=0ℹ️ The jira-config.properties file is not created by default in a new Jira installation. For further details on adding this file and its location, please refer to Advanced JIRA Configuration
Known issue
This solution stopped working in Jira 9.0.0, due to the bug JRASERVER-74440 - jira.comment.collapsing.minimum.hidden is no longer working on 9.x
The bug was fixed in 9.4.6 and 9.8.1 Jira releases, therefore it is necessary to upgrade to either version (or any higher version) for the jira.comment.collapsing.minimum.hidden parameter to work again.
