Uploading Errors (Troubleshooting)

1. HTTP Error
Check to see that your upload does not exceed the maximum file upload size /  100mb  /  3000px x 2000px
Make sure you are uploading a JPG(for images) and a PDF(for Comics).

(The system sometimes times out when uploading a file over 80mb. You can try re-compressing your file. You’d be surprised how small you can get a file with no loss of quality. Try running it through and re-uploading)

Contact support and let us know which file is causing the trouble. We’ll be happy to help. We may have to upload your PDF on our end, so be prepared to send us your file. A Dropbox link or work great.

2. An Error occurred in the upload. Please try again later
Log out and then immediately back in. Then upload. This often clears this error.
If logging out and in doesn’t fix the issue, you can try uploading through an incognito window.

If neither of these suggestions fixes the error, please contact support. We may need to upload your PDF on our end, so please be prepared to send us a copy of your file. A Dropbox link or ZIP file works great.
