Workaround

NOTE the Navigation Path to the Pages will be changed from the <Old Space Key> to the <New Space Key>

• Create a new space, EXE
  • New Space Name: <original space name> 2
  • New Space Key: NEWKEY
    • Testing found that it is critical to change the Space Key as any operation attempted that re-used the original key while recreating the Space triggered the error again, as historical data is retained to preserve the content history, such as view page history.
• Once the new space has been created Go to the erring space
  • https://<INSATNCE_NAME>.atlassian.net/wiki/display/<SPACEKEY>
• Select:
  • The 3 dot icon in the upper right >> MOVE
    
  • Then Select the the new <original space name> 2 space created previously
  • Select MOVE to complete the move
• Confirm all content moved from the original erring space to the NEW <original space name> 2 Space
• Once confirmed Go here:
  • https://<INSTANCE_NAME>.atlassian.net/wiki/spaces/removespace.action?key=<erring Space Key>
  • Delete the erring Space
• Navigate back to the newly Created Space
  • Select Space Tools >> Overview >> Space Details >> Edit Space Details
  • Rename the space to the original name if desired
• If the new Space needs to be public, the Space permissions will need to be reconfigured
  • Navigate to the Permissions Tab
  • Set Anonymous Permissions to VIEW
