No editable layers

Question

I have a problem editing feature classes from a arcsde database. When i try to edit the features i get the error dbo.default [mypc] No editable layers.  and the warning for each layer Layer or table is not registered as versioned. Does anyone know what i have to do to fix this problem? I have set permissions for each user to have administrative control for the database.
Also when i try to Register As Versioned i get the error Failed to register as versioned. Lock requst conflicts...

Save the Map Document, with the option Unchecked and use the same MXD next time. It will remain that way...

I just want to revive this topic, is there a way we could permanently uncheck the option to Edit a version of the database with the ability to undo and redo? Everytime I open my arcmap, the option is always checked off?

What if you go to Editor drop down menu > Options > Versioning and uncheck the option to Edit a version of the database with the ability to undo and redo?

Hi,
That works for me too. Could you explain why?

Thank you!
