PHP Warning

Hi there,

First off, awesome plugin. One of the few that works in the new Site Editor when placed outside of the main post content loop.

I did run into a strange PHP warning. I did a bit of investigation and cannot seem to figure out why it is occurring.

Warning: DOMDocument::loadHTML(): Empty string supplied as input in .../wp-content/plugins/simpletoc/plugin.php on line 221

However, looking at the code on line 221, you could add a failsafe that would resolve this situation if it ever came up. Something like:

function addAnchorAttribute($html){

  	// remove non-breaking space entites from input HTML
  	$html_wo_nbs = str_replace(" ", " ", $html);
	
	if ( ! $html_wo_nbs ) {
		return $html;
	}

	...

Anyway, just thought I would share. I have manually added the code above and everything works as expected. Thanks again for the plugin.

Best,
Nick
