Your expairiments are in read-only mode when you see padlocks like these:
Padlocks on your My Expairiments page and survey status indicate read-only mode
Why Is My Account in Read-Only Mode?
Your account is in read-only mode when your subscription has ended. Your subscription ends because you cancelled it or because your payment method can not be used.
What Is the Consequence of Read-Only Mode?
Results from your expairiments are available for you to view. Don't worry, nothing is lost.
However, your expairiments are locked, which means participants can no longer access them, and you cannot edit them. Also, you can't create new expairiments.
How Do I Remove Read-Only Mode?
When you resubscribe to pairLab, your account comes out of read-only mode. The locks disappear, your past expairiments are again open to editing and participant voting, and you can create new expairiments.
