I went into my Editor and found the content-single.php and deleted the following code
<?php if ( (function_exists(‘has_post_thumbnail’)) && (has_post_thumbnail()) ) { the_post_thumbnail(array( 200,200 ), array( ‘class’ => ‘post_thumbnail’ )); } ?>
you might have to delete an extra line or two for it to work. It worked right after this. no longer having image show up in blog post.
Found the code to remove.
Fixed my problem.
