When I click on an image it only opens in a browser window and does not pop up in the gallery view to browse through all images in this gallery.
I also get an error message when I activate Lightbox Plus:
"Cannot access protected property simple_html_dom::$doc in /wp-content/plugins/lightbox-plus/classes/shd.class.php" since some server work was done.
I reinstalled both plugins (newest version), I even restored the whole website, but be not able to open the gallery browse view. Any idea what I could do?
