Help! - a client's site has suddenly come down with a fatal error after I just updated to vSlider 4.2
Fatal error: Call to a member function generate_theme() on a non-object in /[...directory path]/public_html/wp-content/plugins/vslider/vslider.php on line 59
(The "[...directory path]" was substituted in this message as it contains the WP username)
In the meantime, I will try to re-install the plugin. I have very little PHP knowledge to troubleshoot the error.
I hope some knowledgeable kind soul knows what the problem is and can offer some suggestions. I've placed the site into "Maintenance Mode" for the time being.
