WooCommerce Single Product Page in Popup Causes Fatal Error

Hello,

When using WPBakery Builder and creating a Woodmart Popup which contains the default WooCommerce “Product Page” shortcode, I get a fatal error upon page update/publish.

Here are the details:

Got error 'PHP message: PHP Fatal error: Uncaught Error: Call to undefined function wc_print_notices() in /var/www/vhosts/dev.cryptocrewuniversity.com/httpdocs/wp-content/plugins/woocommerce/includes/wc-template-functions.php:3622\nStack trace:\n#0 /var/www/vhosts/dev.cryptocrewuniversity.com/httpdocs/wp-includes/class-wp-hook.php(286): woocommerce_output_all_notices('')\n#1 /var/www/vhosts/dev.cryptocrewuniversity.com/httpdocs/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters('', Array)\n#2 /var/www/vhosts/dev.cryptocrewuniversity.com/httpdocs/wp-includes/plugin.php(465): WP_Hook->do_action(Array)\n#3 /var/www/vhosts/dev.cryptocrewuniversity.com/httpdocs/wp-content/themes/woodmart/woocommerce/content-single-product.php(98): do_action('woodmart_before...')\n#4 /var/www/vhosts/dev.cryptocrewuniversity.com/httpdocs/wp-includes/template.php(724): require('/var/www/vhosts...')\n#5 /var/www/vhosts/dev.cryptocrewuniversity.com/httpdocs/wp-content/plugins/woocommerce/includes/wc-core-functions.php(195): load_template('/...\n', referer: https://dev.cryptocrewuniversity.com/wp-admin/post.php?post=3383&action=edit

This is a shame because having this in the popup looks really nice.

I am using PHP 7.2.7 and WP 5.2.2 with Woodmart 3.8.2 & WC 3.6.5.

This occurs on any installation of Woodmart, so it’s definitely an issue with the theme’s custom elements interacting with WooCommerce’s default shortcodes within WPBakery Builder.

Just an FYI.

Hello,

Could you please disable all plugins that are not related to our theme and provide us your admin and FTP access so we can check it?

Thank you in advance

After testing, we’ve found the culprit.

This issue is related to a conflict with Yoast SEO, both the Free & Premium versions.

Because Yoast is the most popular SEO plugin for WordPress, can we expect a fix from Xtemos so we can do popups with WooCommerce shortcodes and still have the best SEO system for WP?

Thanks,

Jesse

Hi,

Provide us with a list of steps on how to reproduce it on your website.

Thank you in advance.

I have created a site specifically for testing this issue.

Yoast SEO is currently disabled. Look for the page called “Testing” as this is where the Woodmart popup is setup to contain a WooCommerce Product Page WPBakery element.

You should have no problem saving/updating this page.

Now enable Yoast SEO in Plugins and try saving/updating this page. You will get the white screen fatal error shown in OP, which forces you to hit the back button in your browser. You should see that your changes were in fact saved, but this white screen is a big issue.

This is true for both Free & Premium Yoast SEO. We went through every plugin we use to determine this is the case.

Hi,

Yes, we see the error now. Could you please check how it works with default WordPress theme without the popup element? Only the single product page. If the problem happens only with WoodMart, please, send us your FTP access.

Regards

Yeah, this is definitely not the issue. It only occurs with the Woodmart Popup + WooCommerce WPB “Product Page” Shortcode Inside Popup + Yoast SEO (Free/Premium) enabled.

What are your thoughts on the above, since you were able to replicate the issue?

Try to add the following PHP code snippet to the child theme functions.php file

add_action( 'woocommerce_before_single_product', 'woocommerce_output_all_notices', 10 );

and edit the file woodmart\woocommerce\content-single-product.php and remove the following code from there http://prntscr.com/ol1k20

Hello,

This has fixed the issue. Thanks!

Are you going to include this in the next Woodmart release?

Jesse

Currently, we will have to investigate the issue more so we suggest you to keep the fix. You can also copy that file to the child theme.
