I updated my site to CB 1.3.1 and received an error with a warning failed to move file. Following suggestions on the forum, I went into the Joomla global configuration and set the enable ftp to No. The update then worked fine.
I set the enable ftp setting back to Y, but when I try to login to the FTP site (using winscp), it gives me an access denied.
Did updating CB change my ftp password? It was working fine right before I did the update.
