It seems that since upgrading to php8 $attr does not always arrive as an array. This is what I wrote: * ``` public function vc_shortcode_output_filter( $output, $obj, $attr ) { if ( is_array($attr) ): $attr += ['awb_after_vc_row' => 'false']; else: $attr = array('awb_after_vc_row' => 'false'); endif; if ( $obj->settings( 'base' ) === 'vc_row' ) { $attr['awb_after_vc_row'] = 'true'; $output .= NK_AWB_Shortcode::get_shortcode_out( $attr, '' ); } elseif ( $obj->settings( 'base' ) === 'vc_column' ) { $attr['awb_after_vc_column'] = 'true'; $output .= NK_AWB_Shortcode::get_shortcode_out( $attr, '' ); } return $output; } ``` * Hope this helps. * Plugin Author [nK](https://wordpress.org/support/users/nko/) * (@nko) * [4 years, 7 months ago](https://wordpress.org/support/topic/php-8-44/#post-15367265) * Hey. * Can you re-test it on a fresh installation without 3rd-party plugins and with a standard Twenty theme? Make sure you use the latest WPBakery version (6.8.0). * I have checked the code of WPBakery and they are always returning an array for this attribute. The only reason may be in the wrong filtering (maybe from a 3rd- party plugin). * In case you still will see an error, can you export your page shortcodes from content, I want to look at them locally. * Regards, nK. * Thread Starter [jckuffner](https://wordpress.org/support/users/jckuffner/) * (@jckuffner) * [4 years, 7 months ago](https://wordpress.org/support/topic/php-8-44/#post-15367713) * I would think the error is coming via [https://help.us-themes.com/impreza/us-core/](https://help.us-themes.com/impreza/us-core/)– see “/plugins/us-core/” in the error log. It’s a commercial plugin to support Zephyr & Impreza VC themes. I’m sure I won’t see an error if I install AWB on a fresh WP copy. * Plugin Author [nK](https://wordpress.org/support/users/nko/) * (@nko) * [4 years, 7 months ago](https://wordpress.org/support/topic/php-8-44/#post-15367976) * If this really comes from their code, they definitely should fix it.
