Problem on order change status with multicurrency

This thread is resolved. Here is a description of the problem and solution.

Problem:
If you're experiencing an issue where the price in the secondary currency (US dollar) is incorrect when updating the order status from processing to completed, and it seems to ignore the dot in the exchange rate, resulting in incorrect price calculations.
Solution:
We recommend updating your WooCommerce Multilingual & Multicurrency plugin to the latest version, 5.5.0, which includes bug fixes and improvements that might resolve this issue. You can find the latest version under My Account -> Downloads on our website. For instructions on how to update, please visit http://wpml.org/faq/install-wpml/.
If you do not see the updates available, try clicking the "Check for updates" button in the Plugins → Add New Plugin → Commercial tab. After updating, if the problem still occurs, we suggest trying to replicate the issue on a test installation. Please ensure to back up your database before proceeding.

If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the issue persists, please open a new support ticket at WPML support forum for further assistance.

nikolaosM	Background of the issue: I have enabled multicurrency with a manual exchange rate in my WordPress site using WPML. I am testing the functionality by placing orders. The default currency is set to euro, and US dollar is the secondary currency. The manual exchange rate is set to 1.084. I am experiencing an issue when updating the order status from processing to completed. The issue can be seen on this page: hidden link Symptoms: When I update the order status from processing to completed, the price in the secondary currency (US dollar) is incorrect. It seems to ignore the dot in the exchange rate. For example, a product with a default price of 100€ shows as 112$ in the processing order email but changes to 1084$ in the completed order email and in the WooCommerce admin order edit page. Questions: Why does the price change incorrectly when the order status is updated from processing to completed? How can I ensure the exchange rate is applied correctly in all order statuses?

While you are waiting for one of my colleagues to take this ticket and work on it, let me provide you with first debugging steps or if I can perhaps help with the issue quickly. Please try using a comma, instead of a dot. Instead of using 1.084 for the exchange rate, use 1,084. Let me know if that fixes it. If that does not help, one of my colleagues will soon come to continue support.

Andrey WPML Supporter since 06/2013 Languages: English (English ) Russian (Русский ) Timezone: Europe/Kyiv (GMT+03:00)	I appreciate your patience. Does the same issue happen if you temporarily disable all the plugins except WPML, WooCommerce Multilingual, and WooCommerce? A similar issue has been reported to our developers. Take a look at the top of this ticket, the content in the yellow box is one solution that has worked for a few clients: https://wpml.org/forums/topic/admin-order-currency-unit-price-is-wrong-2/ If that doesn't work, try unchecking the WooCommerce->Settings-> Enable tax rates and calculations (if that is an option for you). If those don't work, please try the following workaround and let me know your results: In the file: wp-content/plugins/woocommerce-multilingual/inc/currencies/class-wcml-multi-currency-orders.php Go to the line if ( 'total' === $key && ( $item->get_total() !== $item->get_subtotal() \|\| $this->total_is_changed( $item ) ) ) { Remove or comment out \|\| $this->total_is_changed( $item ) Before making any changes, please ensure that you back up your database first.

nikolaosM	Hello Andrey, I only have the basic plugins enabled and a default wordpress theme, also I have the taxes calculation option disabled. Also in the path you provided there is no line like the one you mentioned. Please have a look at the file you mentioned and tell me again what I need to do. The ticket you metioned is from a year before, many updates since then. Thanks!
