Mobile drop-down menu missing

Hi,

I noticed an error on your website, while checking it with W3 Validator:

Could you clarify where those errors are occurring?

Line 848/849 ,

<nav id="nav" class="nav-holder">
<ul id="nav" class="menu">

You have a plugin that is not loading. Using the file manager provided by your host change wp-content/plugins/revslider to wp-content/plugins/revslider-old.

The revslider had already been removed. I don’t think that was the problem.

You still get some loading errors from that plugin. Check:

Should I delete that reference to revslider?

From where is that call made?

You should try to see how things are going with revolution slider turned off.

The whole situation is complicated by the fact that there is Revolution Slider that came with the theme that is being used.

My problem came when I stupidly activated a Revolution Slide plugin at the same time (during a switch in theme). When I reverted the theme – both Revolution Sliders collided. Now, the slider doesn’t appear anywhere and the editing pages don’t even render properly.

I’ve opened a ticket with the plugin support.

Interfering slider problems broke some things. All good now.
