Problem: You are trying to update the WPML Multilingual CMS plugin and encountered an error: PCLZIP_ERR_BAD_FORMAT (-10) : Invalid archive structure. Solution: If you're experiencing this issue, we recommend trying to upload other plugin zip files, such as WooCommerce or Akismet, to check if similar issues occur. This can help determine if the problem is specific to the WPML plugin or a broader issue with your WordPress setup. Additionally, check your WP MEMORY LIMIT under Tools > Site Health > Info. If it's still set to 40M, you might need to increase this limit as it could be affecting the plugin update process.
Please note that this solution might be outdated or not applicable to your specific case.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 the problem persists, please open a new support ticket at WPML support forum for further assistance.
