Layerslider failed to open stream

The notification is gone.

The layerslider is still broken. It loads and then flashes and then when the first background slides off screen the next slide does not follow in behind it. The area goes blank until the next slide animation happens. At that point the next slide flashes on the screen and animates across the screen, then the next slide is again blank. None of the text layers display at all.

There is also a notification in the browser console:
GET https://www.infostructures.com/wordpress/wp-content/themes/enfold/config-layerslider/LayerSlider/static/layerslider/skins/fullwidth/shadow.png 404 (Not Found)

Is that related?

This exact installation is currently working perfectly in our DEVELOPMENT environment. This web server is a clone of the DEV server. It worked until I did my first SAVE from the Enfold Theme settings page. That SAVE seemed to hose the LayerSlider.

Any ideas on what is going on?

Why is there always this “shadow.png missing” error in the console?

I replaced the header and footer files in the child theme folder. The LayerSlider still loads twice. And now I am getting a lot of Warning notifications in the footer.

Goes on and on ... way too many lines to put in here.

Here is the code at line 2030 in C:\inetpub\wwwroot\wordpress\wp-includes\wp-db.php

		if ( ! empty( $this->dbh ) && $this->use_mysqli ) {
			$this->result = mysqli_query( $this->dbh, $query );
		} elseif ( ! empty( $this->dbh ) ) {
			$this->result = mysql_query( $query, $this->dbh );
		}
		$this->num_queries++;

So I opened up the admin side and made a trivial change in the theme editor so that I could hit SAVE because sometimes that seems to jiggle the theme back into shape. And that did indeed get rid of all the Warning notifications in the footer.

But now the LayerSlider still loads twice. And when I try to use a slider with text layers and slice effects, they fail. Text displays in the upper left – piled on top of each other – and the background images do not display or slide correctly.

Can you take another look at it?

Thanks!

Yes it was related to a compression setting in the Enfold theme settings. Disabling the compression fixed the Layerslider. Thanks
