I'm pretty new to blogging and the really technical stuff, and I can't figure out how to add a StumbleUpon button, even though they have instructions on their website. This is what the website says to do:
Tips for adding StumbleUpon badges
* Edit single.php of your WordPress theme.
* Find the following line (or similar line, depending on your theme file) in single.php or theloop.php:
<?php the_content("<p class=serif>Read the rest of this entry</p>"); ?>
* Immediately after the line, add the code above:
* Save and upload single.php back to your WordPress theme folder. Done!
How do I do that? How do I "edit single.php of [my] WordPress theme"? I'm sorry if I sound ignorant, but that sentence makes no sense to me. Can someone please explain it to me?
The blog I need help with is sovereignfugue.wordpress.com.
