Workaround
Please, make a full backup of your site before proceeding.
- Open this file: /wp-content/themes/themify-ultra/themify/themify-template-tags.php.
- Look for line 1824.
- Replace this line:
if ( is_a( $filter['function'][0], 'WPML_LS_Render' ) ) { - With:
if ( is_array( $filter['function'] ) && is_a( $filter['function'][0], 'WPML_LS_Render' ) ) {
