Unlocking a task can be performed by a user with higher project role than the user who locked the task. Thus if a task was signed by a Technician only a User or Owner will be able to unlock the task.
To unlock the task navigate to the locked task and select Unlock task button.
Then input your user credentials and select Sign and unlock task button.
The task will be unlocked and other users with sufficient privileges will be able to perform any further modifications.
