At the same time, another site that uses FOX has the same plugin error:

Howdy!

WordPress has a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins, FOX - Currency Switcher Professional for WooCommerce.

First, visit your website (https://ed2kidz.com/) and check for any visible issues. Next, visit the page where the error was caught (https://ed2kidz.com/wp-admin/customize.php?return=%2Fwp-admin%2Fadmin.php%3Fpage%3Dwoo-cart-abandonment-recovery) and check for any visible issues.

Please contact your host for assistance with investigating this issue further.

If your site appears broken and you can't access your dashboard normally, WordPress now has a special "recovery mode". This lets you safely login to your dashboard and investigate further.

To keep your site safe, this link will expire in 1 day. Don't worry about that, though: a new link will be emailed to you if the error occurs again after it expires.

When seeking help with this issue, you may be asked for some of the following information:
WordPress version 6.9
Active theme: Flatsome Child (version 3.0)
Current plugin: FOX - Currency Switcher Professional for WooCommerce (version 2.4.3)
PHP version 8.4.7

Hello

Try this fix: https://drive.google.com/file/d/1SWkHHppxDeSoow-YPB9ZN-ro7kXc6Eai/view?usp=sharing

Upload file to folder: wp-content\plugins\woocommerce-currency-switcher\classes\Rates\Aggregators

Is this an issue that arises due to Yahoo Rate? If so, should I switch to another rate provider to resolve this problem?

I have two websites that use FOX 2.4.3 and the latest updated version 2.4.3.2, and both have this issue. However, the 2.4.3 version was always fine before.

Or do I have to upload the fix file provided by you to the folders of two websites to solve the issue?

The question is which solution is better for long-term stable use and plugin updates?

Hello

Just update the file I provided: wp-content\plugins\woocommerce-currency-switcher\classes\Rates\Aggregators\YahooRateProvider.php - this should help

later we will do update of the plugin, maybe even on this week

Also yes, you can switch to another currency provider ...

Please provide the plugin update to the [WooCommerce Business Tools Bundle] so that the updated plugin can be used

Thank you
