I’m also experiencing this issue. Disabling Clammr allows the player to show up. Enabling it makes it disappear. No warnings or errors, even in the Chrome debug console.
Using version 1.1.4
As it turns out, one of the most popular starter themes at this time (Underscores) doesn’t load jQuery by default.
For those future time-travellers, add the following to your functions.php file:
/**
* Add jquery support
*/
function jquery_scripts() {
wp_enqueue_script( 'jquery' );
}
add_action( 'wp_enqueue_scripts', 'jquery_scripts' );
If you already have a section for scripts (like the Underscores theme), just add wp_enqueue_script( 'jquery' ); to your existing *_scripts() block.
Would you mind mentioning which plugin you had a conflict with?
