Hello.
Yes the button shortcode doesn’t seem to be working. I have the following implemented on a page.
[color-button color=”orange” url=”https://map.google.com/”%5DTransit: Pacific / 7th Tacoma-Downtown[/color-button]
The HREF is shortened to maps.google.com in this example to show the intention of use. The actual long URL for the map for the link would be placed there. I have used both the long and shortened version of the URL–no luck. I have left the HREF blank and even “#” with no success. The button simply does not show up.
It wasn’t until I added a default URL to the settings panel for the plugin, such as https://maps.google.com, the button appears regardless if their is something in the HREF reference or not. If you have a default URL, the default URL is the ONLY URL the shortcode will display.
Your colored boxes work flawless. I am using your latest version of this plugin and WordPress 3.5.1.
