php 8

Hey.

Unfortunately, I don’t see such an error on the test server. If you can provide more information on how to reproduce it, it will be helpful.

Regards, nK.

Thanks for your response. I will do some more testing and let you know what I find.

Here is the full message I get on the server:

Message:

I managed to create a workaround by adding declarations to vc_shortcode_output_filter. 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.

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.

I would think the error is coming via 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.

If this really comes from their code, they definitely should fix it. Just let them know.
