I recently ran into an issue where a custom theme didn't display PowerPress audio player in excerpts. I found in PowerPress' documentation (
http://create.blubrry.com/resources/powerpress/powerpress-and-your-theme/) a function call to add it, but it kept breaking my website. This is the original code:
<?php if( function_exists('the_powerpress_content') { ?>
<?php the_powerpress_content(); ?>
<?php } ?>
The problem is (wait for it...) it is missing a closing parenthesis. Please update your documentation.
<?php if( function_exists('the_powerpress_content')) { ?>
<?php the_powerpress_content(); ?>
<?php } ?>
All in all, great plugin, great support. Keep it up!
