Nested shortcode doesn't work even when recursively called [closed]

Question

Shortcode 1:

function blue_table($atts, $content = null) {
        return '<div class="blue-table">' . do_shortcode($content) . '</div>';
        return '';
    }

Shortcode 2:

function example_1($atts, $content = null) {
        return '<a class="skinny-popup1 button-example" href="#">example</a>';
    }

What I'm typing in editor:

[bluetable]Make sure that your wall posts elicit some form of feedback. Start the conversation, don't just push information.[example1][/bluetable]

Output for [bluetable] shortcode works, however [example] does not.

Answer 1

It works for me, the test code im using is:

add_shortcode( 'example1', 'example_1' );
add_shortcode( 'bluetable', 'skinny_popup1' );
function skinny_popup1($atts, $content = null) {
        return '<div id="skinnypop1" class="skinnypop"><div class="msgbox"><div class="pop-top"><a class="close" href="#" >close</a></div><div class="pop-content"><div class="cycle-gallery">' . do_shortcode($content) . '</div></div><div class="cycle-nav"><a id="prev" class="ir" href="#">Previous</a><a id="next" class="ir" href="#">Next</a></div><div class="slidecopy"></div><div class="pop-btm"></div></div></div>';
    }

function example_1($atts, $content = null) {
        return '<a class="skinny-popup1 button-example" href="#">example</a>';
    }

Maybe a typo on the function name?
