    I was also having this issue, but was able to get the error to go away after making sure that all bars had the fade out disabled

    I was able to re-enable bartender after removing the Single Button Assistant

    from a user on Curse:

     

    1 hour ago

    Replace lines 417 through 419 of Bar.lua with this (if you get the fade out error, not the single button assist errror)

     

    if bar.overlay:IsMouseOver()

    or (SpellFlyout and SpellFlyout:IsShown() and SpellFlyout:GetParent() and SpellFlyout:GetParent():GetParent() == bar and SpellFlyout:IsMouseOver())

    or (LABSpellFlyout and LABSpellFlyout:IsShown() and LABSpellFlyout:GetParent() and LABSpellFlyout:GetParent():GetParent() == bar and LABSpellFlyout:IsMouseOver()) then

     

    And it'll fix the issue.
