GitHub will automatically disable scheduled workflows when there has been no activity on a repository in 60 days. Since CompatHelper is a scheduled workflow, this means that CompatHelper will be automatically disabled.
If this happens on one or more of your repositories, you will need to manually re-enable the CompatHelper workflow. Otherwise, you will no longer receive CompatHelper pull requests.
Here are the steps to re-enable the CompatHelper workflow on a repository:
Step 1: Go to the GitHub repository.
Step 2: In the navigation bar at the top of the page, click on the “Actions” tab.
Step 3: In the sidebar on the left side of the page, under the heading that says “Workflows”, click on “CompatHelper”.
Step 4: If CompatHelper has been disabled, you will see a message that says “This scheduled workflow is disabled because there hasn’t been activity in this repository for at least 60 days.” Click on the “Enable workflow” button.
Step 5: You will then see the message “Workflow enabled successfully.”
