Kor WPML Supporter since 08/2022 Languages: English (English ) Timezone: Asia/Singapore (GMT+08:00)	Thank you for responding. I've reviewed the logs you provided and haven't identified any issues that would cause the site to malfunction; these logs merely contain PHP warnings. Unless it shows PHP Fatal Error. Typically, a 502 bad gateway error indicates insufficient server resources. Upon inspecting your debug logs, I've noticed that the PHP limit for your "WP Memory Limit" is set lower than the recommended 256MB or the required 128MB, as specified in the documentation available at: https://wpml.org/home/minimum-requirements/. To address this, I kindly suggest contacting your hosting provider to request an increase in the PHP value for you.
