Unknown Error in Bulk Optimization

In the Bulk Optimization when sending a huge request, depending on your server and network speed, it can take a while and timeout can occur. That’s why an “Unknown Error” appears.

Unfortunately we don’t have magic solutions, but here are a few tips:

  • This can be a temporary issue, retry again after a few minutes.
  • This may be because of the number of thumbnails you optimized, try to reduce the number in the Settings Page.
  • Try to optimize the images individually from the media library.
  • In wp-config.php, add this line
    set_time_limit(0);
