[gitlab-org/gitlab] Unable to Edit the Code or Fork

### ROOT CAUSE The issue described is related to the permissions and behavior changes introduced in GitLab 11.3.4. Specifically, the error message "You're not allowed to edit files in this project directly. Please fork this project, make your changes there, and submit a merge request." suggests that the user does not have the necessary permissions to directly edit files in the project. This could be due to the project being protected, or the user not having the appropriate role within the project. ### CODE FIX To resolve this issue, the user should follow these steps: 1. **Fork the Project**: If the user does not have the necessary permissions to edit files directly, they should fork the project. This can be done by clicking on the "Fork" button on the project's main page. 2. **Make Changes in the Fork**: Once the project is forked, the user can make the necessary changes in their forked repository. 3. **Submit a Merge Request**: After making the changes, the user should submit a merge request from their forked repository to the original project. This can be done by navigating to the "Merge Requests" tab in their forked repository and clicking on "New Merge Request." 4. **Review and Merge**: The maintainers of the original project will review the merge request and, if it meets the criteria, merge it into the main project. By following these steps, the user can contribute to the project without encountering the permission issues described in the issue.
