Problem: You are using the latest version of WordPress, WPML, and SVG support, with WPML Media Translation version 3.1.0-b.2 installed. However, you are unable to upload SVG files, encountering a 'Security check failed' error. This issue only occurs with the Media Translation plugin; SVG uploads work fine in the media library. Solution: We have tested and found that using the Safe SVG plugin allows for SVG file uploads and translations, whereas the SVG Support plugin does not. This suggests a compatibility issue with the SVG Support plugin. We recommend trying the Safe SVG plugin to handle your SVG files. If this resolves the issue, it confirms the compatibility problem. If you continue to experience difficulties, please check our known issues page and ensure you have the latest versions of all themes and plugins installed.
If the problem persists, we highly recommend opening a new support ticket for further assistance. You can do so here: WPML support forum.
