The package could not be installed. PCLZIP_ERR_BAD_FORMAT

Hi, Im having this error when installing a theme on my Wordpress.

The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature

They said this might be a server issue, any Idea’s?

I have two questions:

  • Does the file have the .zip extension (rather than some other archive type).
  • What is the size of the file?

  1. Yes it is .ZIP
    1. Size is 7.6MB

UPDATE : I think its a problem with the file, now its working.
