christianS-199	Background of the issue: I installed WPML and expected normal performance. The issue can be seen on this page: hidden link. Screenshot performance report: hidden link Symptoms: After enabling WPML, the WooCommerce site and products slowed down significantly. Only WPML and String plugins are active, and no additional plugins or translations have been added. Normal pages work fine and fast. Questions: Why is WPML causing WooCommerce to slow down? How can I improve the performance of my WooCommerce site with WPML enabled?

Andreas W. Supporter Languages: English (English ) Spanish (Español ) German (Deutsch ) Timezone: America/Lima (GMT-05:00)	Hello, This increase of load time seems to occur only if "WPC Product Bundles for WooCommerce" and "WPML Multilingual CMS" are active at the same time. Please revise the dev site and confirm if I analyzed this correctly. We can then take further steps and try to replicate this issue on a test site. Best regards Andreas

Andreas W. Supporter Languages: English (English ) Spanish (Español ) German (Deutsch ) Timezone: America/Lima (GMT-05:00)	Yes, please let me know if you can confirm my finding and I will set up a test site to try to recreate this issue. Maye even this known issue might be related and we could try applying this workaround: https://wpml.org/errata/woocommerce-product-bundles-php-notice-function-product_type-was-called-incorrectly/ Let me know if I should give this a try.

Andreas W. Supporter Languages: English (English ) Spanish (Español ) German (Deutsch ) Timezone: America/Lima (GMT-05:00)	I have revised the config for custom fields at WPML > Settings > Custom Field Translation. It looks like some fields were still missing to be set to "Copy" - this will make sure that the same options are set between products. Another issue is, that the site has only one active language and this can lead to unexpected issues. By default after setting up WPML always at least two languages should be active. Please activate a second language and leave me a message after so that I can continue testing.
