Uncaught TypeError: Cannot read property 'className' of null 2autoptimize_bacff8

    Hello,

    I installed Autoptimize a while back, and recently also installed Fastest Cache to manage my account with MaxCDN. For whatever reason, lately I have been experiencing issues with my website (e.g., my website is very slow when I try to edit my content). In fact, when I attempt to edit page content via my dashboard, the page fails and I receive an “awe snap” error from Google. Upon inspection, I noticed the following errors:

    Uncaught TypeError: Cannot read property ‘className’ of null
    2autoptimize_bacff87c87acdad4fd3fc3665f271fd5.js:40 [cycle] terminating; too few slides: 1

    My questions are as follows:
    1. Are these 2 plugins compatible (fastest cache and autoptimize)?
    2. Why am I seeing this error and how do I resolve it?
    3. Any other advice?

    Thank you so much for your help and any advice you may have to offer.
    Like others, I appreciate your contribution to WordPress and the WordPress community.
    Dana ??

    stumped is what I am, as AO is never supposed to be active on the dashboard cfr. this code snippet;

    if (!is_feed() && !$ao_noptimize && !is_admin()) {

    !is_admin() means that if is_admin() equals true, nothing happens.

    except if you have some plugin that shows your frontend somehow, when editing in the backend?

    ah, but I just saw here you’re actually using visual composer and that’s a whole different angle ??

    you’ll have to deactivate AO while accessing the site to “compose” by using this code:

    add_filter('autoptimize_filter_noptimize','visual_noptimize',10,0);
function visual_noptimize() {
	if ((is_user_logged_in())||(strpos($_SERVER['REQUEST_URI'],'vc_')!==false {
		return true;
	} else {
		return false;
	}
}

    add this code using code snippets or if you insist to your (child) theme’s functions.php and you’ll be able to “compose” away ??

    hope this helps,
    frank

    there were 2 parantheses missing in Franks solution. this is corrected and working fine with this code:

    add_filter('autoptimize_filter_noptimize','visual_noptimize',10,0);
function visual_noptimize() {
	if ((is_user_logged_in()) ||(strpos($_SERVER['REQUEST_URI'],'vc_')!== false )) {
		return true;
	} else {
		return false;
	}}

    thanks for the correction maltehelmhold (stupid of me not to have tested this), glad it works now! ??
