Problem: You are trying to update or install the Contact Form 7 Multilingual plugin using the OTGS Installer, but encounter an 'Update failed: undefined' error and are unable to proceed. Solution: We recommend checking if the installer is automatically deactivating because it's already active through the core plugin. You can find this under Plugins → All Plugins, specifically in the Commercial tab. Here, you can download and activate the plugin. Alternatively, you can manually download the ZIP file from your WPML account at https://wpml.org/account/downloads/.
If this solution does not resolve your issue or seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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 the problem persists, please open a new support ticket.
