• I have Force Regenerate Thumbnails version 2.0.6 on WordPress 4.7.1. All images uploaded since yesterday are unable to be regenerated its thumbnails by the plugin. The error is: (ID 472) Unknown failure reason.
    The permission of the file after I upload is 644. I tried to change the permission into 777 and rerun the regenerate thumbnails but it still didn’t work.
