Problem: The client is experiencing a fatal error when trying to update WPML String Translation using otgs-installer-plugin.3.1.3.zip, resulting in a frozen screen during the 'activating' process and subsequent fatal errors and notices about incorrect function calls. Solution: We recommend updating the plugins manually. First, download the latest versions from https://wpml.org/downloads/. If your site is down due to the error, navigate to wp-content/plugins/wpml-string-translation, rename the folder to 'wpml-string-translation.deactivate' to regain backend access, then delete and replace the plugin with the downloaded version. Always update the main WPML plugin before updating WPML String Translation. Additionally, ensure you have a recent and working backup before making any changes.
If this solution does not resolve your issue or seems outdated, please check related known issues at https://wpml.org/known-issues/, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins. If problems persist, we highly recommend opening a new support ticket for further assistance.
