With version 2.0.7 of Custom Sidebars I can't define where to show my custom sidebar. As you can see in the screenshot, the options for single entries and for archives are not shown; so, they can't not be selected.
Using Chrome Console, I've seen that the HTML code for those options exists, but it is not shown and can not be selected.
The last version which works in my site is 2.0.3.
I've changed my theme to Twenty Fourteen, but Custom Sidebars doesn't work. I've algo enabled WP debug, but there's no warning message related to the plugin.
