Why is my project locked?
Your account has a limit on the number of active projects at any one time. This limit varies by plan. If you notice that one of your projects is locked, you've reached your maximum number of projects for the plan you purchased. This means you cannot access any of the data in the locked project.
How to know if a project is locked
Look for the padlock symbol next to the project's name on the left-hand side of your screen, as shown here:
When you try to open up the project in the Tracker, a message like the one below will appear:
How to unlock a project
There are two ways to unlock a project:
Upgrade your plan
Select Account > Settings from the bottom-left-hand corner
Select Manage
Select Change your plan
Select Upgrade under a plan with a greater maximum number of projects
Once you Confirm Payment, your subscription will be updated to support more active projects, and your locked project(s) will unlock.
Delete existing projects
You may wish to remain on your current plan and keep the same project limit. In this scenario, your only option is to delete one or more active projects. Doing so will free up your account's project capacity, allowing your locked project(s) to replace those you deleted.
Note: Projects are not archived. This means deleted projects cannot be restored.
Tip: Before you delete a project, you may want to move saved opportunities from that project to another active project so that your data isn't lost permanently upon deletion.
