Hi,
I am experiencing an issue where WPML fails to translate a page. Every time I attempt to translate it, I receive the error message: "WPML could not translate this page" (see attached screenshot). The "Retry" button does not resolve the issue.
Looking at the log you shared. This usually indicates that the server cannot reach WPML’s services. Most often, this happens when the hosting environment blocks outgoing requests.

First, I would suggest deactivating all plugins except WPML, then testing again. Each time you test, I would first make a small edit to the original page, update it, and then try to access the translation editor.
If the issue persists, please ask your hosting provider to ensure that the following domains are not blocked and are whitelisted if necessary:
- wpml.org
- cdn.wpml.org
- api.wpml.org
- api.toolset.com
- cloudfront.net
Once the hosting provider confirms that these domains are accessible, please test the translation editor again.
If this also doesn't help, it’s possible that certain server-side security layers (such as firewalls, mod_security, Imunify360, or similar protections) are interfering with the save process, which could result in the issue you’re experiencing.
I would recommend contacting your hosting provider again and asking them to ensure the REST API is not blocked in any way. Temporarily disable any restrictive security layers for testing. Or whitelist/exclude WPML-related requests from those protections.
