EasyCLA was previously enabled for a GitHub repository, but someone other than the project manager has subsequently disabled it.
GitHub is set up to permit administrators and organization owners to have maximum flexibility, which includes disabling installed applications, such as EasyCLA. To avoid this, you must enable branch protection by after the GitHub organization is added to a project.
You can also add the branch protection rule manually, as described below:
1. As the GitHub organization owner or administrator, go to the GitHub repository that you want EasyCLA to monitor.
2. Click Settings from the top menu.
3. Settings appear with Options in the left pane.
4. Click Branches under Options.
5. Select master for the Default branch. Click Edit or Add rule for Branch protection rules of your organization.
6. Select the following check boxes under Rule settings, and click Create:
Require status checks to pass before merging
Require branches to be up to date before merging
Include administrators
