is_staging_site is deprecated!

Hello tonygao,

Thank you for contacting Woo support.

The message you’re seeing indicates that your site is using deprecated code, specifically the is_staging_site function, which has been replaced by in_safe_mode.

To troubleshoot this:
Disable your active plugins one by one to identify which plugin is using the outdated code.
You can also temporarily switch to the default Twenty Twenty-Four theme to check if the issue is related to your theme.

Additionally, to prevent such messages from displaying, ensure that WP_DEBUG is set to false in your wp-config.php file.

Let us know if you need further help!

Best regards.

After a search, woocommer plugin(s) use s_staging_site. See below:

Hello tonygao,

Thank you for your reply.

I understand that the is_staging_site function is part of the WooCommerce.
It is deprecated (not yet removed) to allow other plugins and theme authors to update their code.

There is a plugin that is calling this deprecated function.
To find out which plugin is using this function, disable your plugins one by one and check the error log. When the affected plugin is disabled the log entries will not be created.

Let me know if you have any questions.

Best regards.

The problem is caused by the “WooCommerce Shipping & Tax” plugin

After disable the plugin, no notice in debug.log. Please fix it!

Hi @tonygao,

After disable the plugin, no notice in debug.log. Please fix it!

First step, please make sure that your WooCommerce Shipping & Tax is up-to-date. Then you can try having only WooCommerce and the WooCommerce Shipping & Tax as the active plugins to see if the same issue persists.

The WooCommerce Shipping & Tax is the latest version. Will try to debug which plugin call it and caused the problem

Hello @tonygao,

Thanks for confirming this. Please let us know how this goes or if you have additional questions.

Thanks!

Based on the following debug trace, it seems the problem is within the plugin, I already uninstalled jetpack but the plugin seems still trying to use it

Hello tonygao,

Thank you for your reply.

To confirm, did you deactivate all the plugins except WooCommerce and WooCommerce Shipping & Tax?

If not could you check again with WooCommerce and WooCommerce Shipping & Tax as active plugins?
I am asking because the code line that is mentioned in the debug trace is catching the call to the deprecated function is_staging_site. This means another code is calling this function.

Please conduct this test and let me know about your results.

Looking forward to your response. ??

After further debug, it seems the problem caused by the plugin “woocommerce payments”

In file: /home/public_html/wp-content/plugins/woocommerce-payments/woocommerce-payments.php

There is code that initialize jetpack even when jetpack not installed

Just updated the WooCommerce Payments plugin to the latest version(8.2.1) and the problem solved.

Hey @tonygao

That’s great to hear and thanks for updating the thread to let us know everything is working as expected again ??
