Somehow the .htaccess file was malformed and that fixed it. Did your people touch this while in there?

Confirmed. Simply deleting that line brought my site back up.

Thank you!

I removed line 435. It worked to help me get back onto my dashboard and reinstall my backup. For anyone wondering, the specific line in the PHP file is

if( ! empty( trim( $element[‘label’] ) ) )

Hi Andy,

I engaged some support for this because there was a time sensitive need. I thought I had sent this privately, but apparently this did not go through.

When I checked plug-ins I neglected to look at the Advanced LayerSlider as that does not reside with the other plugins and simply overlooked it. It is out of date and we’ll be addressing this shortly.

I feel confident that this is where the problem is because the issue began when I reinstalled an old slider.

If that did the trick, here’s the culprit:

It looks like the Layerslider element of Enfold was deregistering jQuery to include an alternate version from the Google CDN. But the way it was enqueing the alternate version made it so that jQuery loaded *after* WordPress tried to load its core scripts. So that was causing downstream javascript errors.

I fixed things by going into the advanced LayerSlider settings and turned off “Use Google CDN version of jQuery”.

The top of that LayerSlider settings page says there’s a newer version, but I don’t know how to update it since it’s a bundled version. It looks like that’s on Enfold to fix:

While deactivating and reactivating solved the problem, I was unable to duplicate this error.

Perhaps this was “just a thing”?
