Welcome to Q&A Forum!
Perform the following troubleshooting:
1.Make that the SharePoint farm is at least updated to March 2013 PU (the Service Pack 1 is recommended)
2.Make sure that the App Management Service is configured and started
3.Make sure that the User Profile Sync Service is working properly. (it’s not mandatory but if it’s already configured, just make sure it’s healthy working
4.The Workflow service account has dbo permission on SB and WF databases.
5.Make sure Workflow Manager 1.0 Refresh (CU2) is installed
If the error still occurs, you can refer to the following links to reinstall the configuration WorkFlow Manager 1.0.
