Plugin version: 1.4.2
WP version: 3.7.1
Found another bug in this plugin that is causing some issues in our environment.
Line 249 in text-blocks.php:
$content = apply_filters( 'the_content', get_post_field('post_content', $id) );
This causes all of our custom the_content filters that were added before text-blocks plugin to be executed.
Was this intentional design choice? I commented this line out for now - seems to work better without that line for us :)
