Everything went well until I uploaded the finished site to my ISP.

ERROR! Failed in extracting zip file
  • I ran installer.php and all tests passed.
  • When it started to install, I got an error indicating that my zip file may be corrupt.
  • I could unzip it locally just fine.
  • I deleted and re-uploaded it again — same problem.
  • The support site for Duplicator had no reference for this type of error.

What finally worked?

  • Rather than using CoffeeCup DirectFTP (v6.9 Build 2014 Full), I logged into CPanel and used File Manager to upload the file.
  • This time everything worked. Not sure why the file was corrupt via FTP but this is just in case anyone else has this issue, try an alternate upload method.
