Error: CSS name already in use

[Ykit]

Hi,

I am trying to edit one of the stylesheet, but after editing, when I click Apply or Submit, the error keeps popping up.
I checked and there is only one stylesheet in the server.
This stylesheet is attached to a template with the same name.
Can anyone kindly advice me for the solution?
Thanks alot!

You could try to changing name as "&" might not be accepted. Always try to avoid special charachters in names even if they might work.
