Hello Aswin,
In some themes, <?php the_content is available in loop.php, not in single.php
Hi Naser.
In some theme(s) may be <?php the_content will be both in loop.php and single.php
but single.php is where the content of post resides. So as to add the +1 button after the content it we have to place after the single.php.
