After update getting this strange error when click on + to add a block

Hi @strongwomancrushing,

The issue you are facing, may be due to a theme/plugin conflict. Follow these steps to determine if there is a theme/plugin conflict:

1. Switch your theme to Storefront.
2. Disable all plugins except WooCommerce.
3. Perform the test to verify whether you’re able to add a block.

If the issue is resolved after switching to Storefront theme and deactivating all other plugins except WooCommerce, the problem may be with the plugins and/or theme you deactivated. To figure out which plugin is causing the problem, reactivate your plugins one by one, testing after each reactivation until you find the one causing the issue.

Please share the following information for further investigation:

1. System Status: You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”. Once you’ve done that, paste it here in your response.
2. Fatal Error Log: A copy of any fatal error log found under WooCommerce > System Status > Logs (if available).

Here are our fatal errors log:

Hi @strongwomancrushing ,

2023-03-03T10:37:29+00:00 CRITICAL Uncaught Error: Class 'WP_HTML_Tag_Processor' not found in /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/woo-gutenberg-products-block/src/Interactivity/woo-directives.php:112

This error was due to a bug with the WooCommerce Blocks version 9.7.1 which was released earlier today. Our developers have already released a fix for this in version 9.7.2.

Please can you update your WooCommerce Blocks plugin to the latest available version (9.7.2) and see if this resolves the issue you are experiencing.

Cheers!
