 * Hi, does “Error 404” mean the file can’t be found? Can’t figure out why some 
   images in a folder will convert but others receive this error. Also receiving“
   Error 0.” I disabled firewall and security plugins, but still no luck. All image
   extensions checked under General tab.

 * Hello, wow, I have no idea, that should not happen.
 * You can receive Error 500 when server has not enough resources to process some
   huge image, but that’s it…
 * In my opinion, someone was doing something on website and removed some images
   during the conversion process… or there are some strict permissions on some images…
   otherwise I can not imagine how 404 can appear.
 * And I’ve never heard about Error 0.

 * Hi, thanks for responding. Even when I changed the folder/file permissions to
   777, it still wouldn’t work. It’s only converting .png but not the .jpg files(
   I’m certain it’s toggled on) and I’m the only one who has access to the server/
   images. It seems like a great plugin. Even though it didn’t work fully on my 
   site, having the .pngs converted is still a big help.

 * This is very interesting and I have no idea how it’s possible, but as I’m not
   allowed to ask you for an access to your server on this forum, then I’m afraid
   I can not help you more.
 * It would be possible to investigate this by asking you to do various tests, logs,
   changes, etc… but it would take a lot of time, that unfortunately I can not afford
   right now…
 * If you will be interested to solve this problem in 1-2 months, then we can maybe
   continue this thread… let me know 😉
