Problem: The client experiences a '503 Service Unavailable Error' when trying to save a page with a lot of content in the admin area, specifically the home page. The error seems to be related to server memory issues, despite having sufficient memory limits set (256M and 512M). Solution: We recommend increasing the 'max_execution_time' to 300 or higher to potentially resolve the issue. Additionally, it's crucial to contact the hosting provider to check the server logs for more detailed insights, as the error is typically related to server-side issues. If the problem persists, we suggest editing the primary language page and unchecking the 'ACFML synchronization of translations - Keep repeating fields and flexible subfields in the same order as in the default language' option. This adjustment should allow the page to be updated without triggering the error.
If these steps do not resolve the issue or if the solution seems outdated or irrelevant to your case, please visit our support forum at WPML Support Forum for further assistance. We also 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.
