Problem: If you're experiencing issues with registering and starting WPML via the installer OGTS, and encountering a 'cURL error 28: failed to connect to api.wpml.org port 443', this might be due to your hosting provider blocking certain domains necessary for WPML's operation. Solution: First, check if there are any connectivity issues with WPML's servers by navigating to WPML > Support > Installer support in your WPML dashboard and clicking the 'check' button. If you see any red X-ses, contact your hosting provider to ensure that the following domains are not blocked: - wpml.org - cdn.wpml.org - api.wpml.org - api.toolset.com - cloudfront.net For more details, refer to our documentation on connectivity issues at https://wpml.org/faq/wpml-plugin-cannot-connect-to-wpml-org/. If manual installation is necessary, download the WPML plugin, upload it via cPanel > File Manager, and extract it to ensure it appears in the WordPress plugins directory.
If these steps do not resolve your issue, or if the solution seems outdated or irrelevant to your specific case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the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 further assistance is needed, please open a new support ticket at WPML support forum.
