There has been a critical error on this website. Please check your site admin em

Errors like this are logged. Check the error log on your server. If you can’t find the log, please contact your host.

Meantime, enable wp_debug and wp_debug_log and after an error, look at wp-content/debug.log to see if anything gets logged there. https://www.ads-software.com/support/article/debugging-in-wordpress/

You can also try this: Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.

If you cannot access wp-admin, there are other ways to deactivate plugins:  https://www.ads-software.com/support/article/faq-troubleshooting/#how-to-deactivate-all-plugins-when-not-able-to-access-the-administrative-menus

I have also faced this error in the past. I would recommend you to check error logs, check if you installed any new plugin, or contact your hosting support.

I checked my email and found this error

how can i fix it as i have no knowledge of coding

I recommend reporting the problem at https://www.ads-software.com/support/plugin/wpcargo/ so the plugin’s developers and support community can help you with this.

The support teams sent me a message that they have updated my wordpress but the same error is the there. This is their message

Howdy! Your site at https://asuthai.com has been updated automatically to WordPress 6.3.1. No further action is needed on your part.

Update them now: https://asuthai.com/wp-admin/ The WordPress Team

You’ll have to wait for the plugin’s support to reply: https://www.ads-software.com/support/topic/wordpress-org-forums-there-has-been-a-critical-error-on-this-website/

Or, switch to an alternative plugin.

which one is an alternative plugin

I’m not sure myself for this, what I mean is find another plugin that does what the broken one does (without the whole broken part, of course).

With that said, while I don’t know the specifics, if you’re using WooCommerce, you might find an alternative here: https://woocommerce.com/product-category/woocommerce-extensions?categoryIds=28685&collections=product&page=1
