Problem: If you're experiencing issues with translating new content from Czech to English using the Advanced Translation Editor (ATE) and previous solutions are not working, it might be due to server output compression. Solution: We recommend checking if output compression is enabled on your server as it can interfere with ATE. You can switch to the Classic Translation Editor temporarily (WPML → Settings) to test if the issue persists. If so, the server is likely returning binary/compressed data instead of plain text. This issue cannot be resolved on our side and requires a change to your server configuration, followed by a server restart. We suggest contacting your hosting provider to adjust the server settings.

If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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 issues persist, please open a new support ticket at WPML support forum.
Problem: If you're experiencing issues with WPML Automatic Translation where updating content in the primary language does not load for translation and shows the error message 'Unable to retrieve job details', this might be due to Gzip compression enabled on your server. Solution: We recommend asking your hosting support to disable Gzip compression. You can find more details on this issue in our errata page: Translation jobs not synchronised when Gzip compression is enabled. After disabling Gzip compression, restart your server. Once your site is up again, edit the original content, save the page, and try to translate it again. If the problem persists, please do not hesitate to contact us for further assistance.

Problem: If you're experiencing issues with translating content into English using WPML, where updating content in the primary language (Czech) and then switching to ATE results in the content for translation not loading and displaying the message: 'Unable to retrieve job details,' it might be due to the translation job containing no translatable data. This issue could be evident across multiple sites using the WPML plugin. Solution: We recommend checking the .xliff file generated by WPML. If the
<body>
element within the .xliff file is empty and the 'wpml-words-to-translate-count' is '0', it indicates that WPML is unable to extract any translatable content. This could be due to server-side issues rather than a problem with WPML configuration, plugins, or themes. Possible server-side causes include multiple applications of output compression (e.g., zlib.output_compression in PHP combined with server-level gzip/Brotli), modifications by security or performance layers (e.g., WAF, CDN, reverse proxy, or caching layer), or incorrect headers or content encoding (e.g., globally applied 'Content-Encoding: gzip'). To resolve this, contact your hosting provider, explain the issue, and ask them to investigate how responses are encoded and compressed on the server. This step is crucial especially if the issue affects multiple sites, suggesting a shared server configuration problem.
