What does Error 0 mean?

    I ran this plugin for the first time. I have a lot of images and it took a few hours. The first 3000ish images worked fine. Then it skipped about 1000 images saying just error 0, then it finished the final 2000 images with no issues.

    When the error 0 happened, it provided no image ID like it does when there are some other errors.

    Any ideas?

    I believe that means there was a communication error with the server that didn’t return a valid HTTP status code. Something like a connection refused or timeout could potentially cause that error. If your PHP timeout is lower than 60, I’d see if you can bump it up to 60 or 120 and see if that helps.

    Two things you can do to troubleshoot further:

    1. Pay attention to how long it takes for each status message to appear. If it is 30 seconds or more, then it’s likely a timeout. If it’s less than 10 seconds, then it’s probably some other connection issue or temporary problem with the server.
    2. You can check the actual AJAX responses like I show in our video here: https://www.youtube.com/watch?v=lEhJ5w4arWE (the video shows EWWW Image Optimizer, but the same ideas apply)
