    Hi, I’m getting this error when switching between slideshow/thumbnails:

    Warning: preg_match(): Compilation failed: unrecognized character after (?< at offset 21 in /var/www/vhost/essentialinstitute.org/home/html/essential/wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/router/mixin.url_manipulation.php on line 161

    This is very disturbing…
    Any solution?
    I’m on 3.7.1

    Thanks
