Getting a Blank Page when I use Visual Selector

<div>There are a number of websites that I want to crawl that I get a blank page when I select  the Crawling Restrictions and then select the Visual Selector on the section:</div> <div class="bws_help_box bws_help_box_right dashicons dashicons-editor-help cr_align_middle"></div> <b>Seed Page Crawling Query Type:</b>   Is there a way to bypass this or to resolve this?, as about 50% of the websites I want to crawl and select via Visual Selector it gives me back this error.   Here is an example: https://www.bizjournals.com/orlando/news/residential-real-estate This particular page gave me back this message instead of a blank page:   <h2>Why am I seeing this page?</h2> The website you are visiting is protected and accelerated by Incapsula.
