can you elaborate?  there are no simple press ‘accounts’… they are simply wp users…  are you saying you deleted the wp user?  where are you getting that message?

are you running 5.4.1?

Yes, I deleted the wp user and I am running Simple Press 5.4.1.  It no longer shows up in “User”, but it still shows up in Simple Press.  

When I turn on “spThisMember” under Data Inspector, it gives me this:

Inspect: spThisMember

did you happen to delete the user from wp before you had 5.4.1?

you can go into  your db and delete the user from the sfmembers table…  for user_id equal to the id you have for that user…
