If you are stuck uploading files in FileZilla that it repeats the progress bar but not happening anything, and saying “File Transfer failed after transferring XX bytes” in the status log, then one of the possible reasons could be the limit has been reached in your FTP. Most likely, the file(s) you were attempting to upload has exceeded file size (Quota) in FTP account/user. You can request the webmaster of the website (or do it yourself if you have access) to change the file limit to ‘unlimited’ as below.

Change FTP file size limit on cPanel

1. Go to the server side and enter cPanel
2. Find FTP Accounts
3. Find your FTP account and increase the Quota (File size limit) ‘unlimited’ if possible.
