Flexsider does not display upon updating plugin

Preview does not work – shows a white (blank) page.
Also, the entire slider itself is no longer displayed on my webpage (I am using an image only flexslider inserted via shortcode).

Upon inspecting elements for the page, the code is there for the slider, but for some reason, there is element styling of ‘display:none;” for the <li> element that houses the actual image. Code in page:

<div id="metaslider_1498" class="flexslider">
   <ul class="slides">
     <li style="display: none; width: 100%;" class="slide-2770 ms-image">
      <img src="https://domainname.org/file.php" height="150" width="150" alt="" />
    </li>
  </ul>
</div>

Where is that ‘display:none;” being brought in and how can I remove it?
No change in anything else on the site except updating the plugin. Using the free version, and have been using it for years with no problem.
