# System property error

Troubleshoot a system property error that occurs while registering a target instance.

## Condition

By default, `glide.db.clone.allow_clone_target` is enabled on instances whose name ends in Dev, Test, Stage, UAT, or QA. An error occurs if the property isn't set to `True`.

**Note:** If it's a production instance, set this property back to `False` to avoid accidental clones over production in future.

## Cause

The `glide.db.clone.allow_clone_target` system property is set to `False`.

## Remedy

## Procedure

1.  Navigate to **All** > **System properties** > **All properties**.

2.  Search for `glide.db.clone.allow_clone_target` in the system properties list.

3.  Select the property.

4.  If the value is set to `False`, set the value to `True`.

5.  Select **Update**.
