The sk-icon-menu is showing a green check mark instead of the menu icon.
I have been able to reproduce this issue and will let our developers know about it. Only certain themes are having this problem. For example, I can see the problem on “Classic” theme but not on “Clean Green” or custom.
Thank you for bringing this to our attention.
I use a custom style sheet
I would assume that custom works dependent upon what you make it look like. Hopefully our developers will catch how certain options work and others do not.
