Hello, welcome WP/LR Sync 1.0! 🙂 I have added support for WPML Media, there are a few enhancements (such as updating the metadata on the WordPress side if they are completely empty while syncing).
Since many users encounter the error “Check your PHP logs”, I tried my best to add some more friendly errors. Basically, those errors mostly come from PHP timeouts (the server cuts the process when it is taking too long) or when the size of the file is too big (PHP has maximum settings for this as well). This is usually to debug however and there are always a solution. Don’t hesitate to contact me or to comment here 🙂
