ProcessMaker Forum | BPM Workflow Simplified

I created a WF and set it to private. Now I am unable to view the workflow (it has disappeared). I can see it when trying to copy a trigger from it to a different WF but the actual WF is no longer accessible. Any suggestions to make it visible? Thanks!

I think you are confusing terms. "workflow" is the default name for the workspace (which has it own database and set processes and users). If you selected the "private" option in the Process Design Access property of the process, then only the user who originally created the process may open it for editing. You need to login as that user in order to see that process in the list when you go to the "Designer" menu.
If you can't remember which user created the process, then you need to look up the user's ID in the database in the PROCESS.PRO_CREATE_USER field and then look it that user's usernamer in the USER.USR_UID field like this:

SELECT U.USR_USERNAME FROM USERS U, PROCESS P WHERE P.PRO_TITLE='My process title' AND P.PRO_CREATE_USER = U.USR_UID;
