Version 9.0 is causing a CRITICAL ERROR

Hi @showapps,

I’m sorry to hear you’re having issues with your website after the latest WooCommerce update.

There’s been a lot of reports about issues with the legacy API. One of the current workarounds is installing the update manually through the plugin’s zip file. You can download it here and upload it to your site by going to your WP Admin > Plugins > Add New > Upload, then select the file.

More details here:

• https://github.com/woocommerce/woocommerce/issues/48587

I hope this helps!

Could you please provide a method to effectively disable the auto-update? We can perform the update manually when we have time.

I tried to update manually and that did not resolve any of the issues.

Hi @blacksnow

You can add the following code snippet in your child theme’s?functions.php file to disable the automatic updates:

add_filter( 'auto_update_plugin', '__return_false' );

Hey @ladysyren

In this case, navigate to woocommerce/includes folder and rename or delete the class-wc-api.php file.

Alternatively, access your site’s root through your hosting file manager or FTP. Next, locate and delete the WooCommerce plugin folder. After that, you can download WooCommerce from here and re-upload it.

I hope this helps! If you have any other questions, feel free to ask.

I tried using “add_filter( ‘auto_update_plugin’, ‘__return_false’ );”.

But woocommerce can still update by itself.

My webshop encountered the same 9.0.0 update critical error as countless others. The mentioned current workaround for the issues with the legacy API “installing the update manually through the plugin’s zip file” doesn’t work. Plugin won’t upload, even after I changed the maximum file size for uploads. Also Woocommerce keeps updating automatically daily, even though it is set not to. So I need to rollback daily as well. When is a bug fix expected?

Hi @boriskrielen

Sorry to hear about the issue you are experiencing.

However, to align with forum best practices, please create a new topic so that we can address your issue(s) separately.

You can create a new thread here:?https://www.ads-software.com/support/plugin/woocommerce/#new-topic-0

Kindly elaborate further there, on the issue(s) you’re experiencing, if this solution worked for you, along with this one.

Thanks for understanding!

We’re sorry for the trouble with 9.0, but are also pretty puzzled by it. If you haven’t already done so and can take a moment to share a note about who your web hosting provider is, and also your system status report (we are particularly interested to know which other plugins are present), we’d really appreciate it. Thank you!

I’m having the EXACT same issue with WooCommerce 9.0.0 as everyone described.

9.0.1 is now available, and updating to that version should solve this issue. However, we’d still be really grateful if impacted users could share:

• A list of other plugins that are active, which can be obtained via the System Status Report.
• A note of who your web hosting provider is.
