I would be glad if you could help me with the following issue. I recently updated my WP version to 3.5.1, because I wanted to change my theme to the responsive Gonzo theme.
Now that the update is done whenever I try to upload the theme it shows this message:
The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature
What can I do about it?
Thank you in advance
