My "post an idea" button disappeared

This is my site: http://earthpossible.com

In the header, I had a button that said. "Post an idea."

That button has disappeared.

 

Hello,

You have hide that button so that button is not displaying, see screenshot.



You can see that button again to apply following CSS code in Custom CSS sections.

Code:

.grid_8.omega {
display: block !important;
}

It will resolve your issue.

Thanks & Regards
