colourI	Tell us what you are trying to do? We received an email from you saying that we had to update to WPML 4.6.1 due to a recently discovered vulnerability. So we updated the plugin and had to disable it because it causes a fatal error. We tested the updates first on hidden link

Waqas Bin Hasan Supporter Languages: English (English ) Timezone: Asia/Karachi (GMT+05:00)	Hi, Thank you for contacting the support. Before proceeding further, may I ask you to try the following? IMPORTANT: Take full backup of your website and database beforehand. It is highly advised to try the following on a staging/dev site first, so your live website isn't compromised. - Deactivate all plugins except WPML and its addons and check for the issue. - Activate each plugin one-by-one, while keeping check on the issue after a plugin is activated. This way you'll be able to pinpoint a plugin having a conflict (or problem), if any. You can also check for plugin compatibility with WPML at https://wpml.org/plugin/. - If the problem persists, repeat the above steps with a default theme of WordPress (i.e. 2023). - Also check the browser's console for any JavaScript errors. If you find any, copy that in your next reply. See https://wordpress.org/support/article/using-your-browser-to-diagnose-javascript-errors/ for details on how to find these errors. Please let me know and I'll try my best to further assist you on the matter. Regards.

Waqas Bin Hasan Supporter Languages: English (English ) Timezone: Asia/Karachi (GMT+05:00)	Hi, Thank you for the updates. Looks like this happened due to some corrupt plugin file which may happen during an update, due to a broken or timed out connection. To fix this, try these steps: IMPORTANT: Take full backup of your website and database beforehand. It is highly advised to try the following on a staging/dev site first, so your live website isn't compromised. 1) Deactivate existing WPML plugins. 2) Connect to your site via FTP and browse to the /wp-content/plugins/ folder. 3) Delete WPML plugins folders. 4) Download the latest versions from https://wpml.org/account/downloads/. 5) Unzip the downloaded files in separate folders, usually when you unzip the file, it creates a folder with the name of the plugin, with zip file's content extracted into it. 6) Upload the extracted (unzipped) folder(s) via FTP, to the /wp-content/plugins/ folder. 7) Go to WP Admin -> Plugins and Activate. Please let me know if this helps resolve the issue. Or I'll try my best to further assist you on the matter. Regards.
