Hi daro1920,

Thanks for using Slider Revolution. What you’re experiencing isn’t a known issue and could be caused by some conflict with another 3rd party plugin. Kindly go through this conflict test and see if it helps. Also, make sure that you’re using the latest version of the plugins, theme, WordPress, and PHP.

This problem appears to be caused by upgrading to PHP 7.1.0. See https://wordpress.org/support/topic/fatal-error-uncaught-error-operator-not-supported-for-strings/

To resolve the issue with the Slider Revolution failing to load in Wordpress I had to manually edit the following plugin file:
\wp-content\plugins\revslider\includes\framework\base-admin.class.php

On lines 141 I changed the line from this:

self::$arrMetaBoxes = $box;

to this:

self::$arrMetaBoxes = array();
self::$arrMetaBoxes = $box;

@ThemePunch-Support-K @themepunch needs to fix this!
