I am using the_content method and it returns me an error:
“Warning: count(): Parameter must be an array or an object that implements Countable in C:xampphtdocswordpressblogwp-includespost-template.php on line 317”

and this is the code:

<div class="b-bottom">
     <p><?php the_modified_date('F Y') ?> | <a class="span_link" href="#"><?php the_modified_author(); ?> 
 </a></p>
     <p class="sub"><?php the_content();?></p>
</div>

I didn’t change anything in post-template.php!!
what is the problem?!
