This from a yoo_theme support thread:
Step 1: Make a copy of the file below:
/yoo_theme_wp/warp/systems/wordpress/layouts/_post.php create the
/styles/STYLE-NAME/layoutsdirectory, copy the file in there and start adding your own PHP code.
Placing the <!–more–> will always show the text link for more content as well as serve as a way to identify where the post content should be cut off on archive / search pages. If you place the <!–more–> tag at the end of the post content, the text link for more content will still display.
In addition to Bruce’s suggestion, I’d use the following line instead:
<div class="content clearfix"><?php the_content(__('Continue Reading', 'warp')); ?></div>
This will preserve your theme translations via the theme provided PO file.
Also, remember to remove or comment out the line below:
<a href="<?php the_permalink() ?>" title="<?php the_title_attribute(); ?>"><?php _e('Continue Reading', 'warp'); ?></a>
