Reply To: PCLZIP_ERR_BAD_FORMAT (-10) Error

Hello,

Please try to upload the theme in the Dashboard > Appearance > Themes.

You would better do that on a staging site first to make sure everything works well. In any case, please make the full backup of your live site.

As I said, you had a very old theme version, you have not updated the theme long. A new version may change your site, I did not want you to see something unexpected on your live site, which is why I suggested testing on the staging site.

When you update the theme on time and your current version is not very old, the update is a click and no problem in most cases.

This is a common practice to update the theme on the staging site first, to see if everything is compatible even thou, site owners update the previous version to the newest one.

If you have any questions please feel free to contact us.

Best Regards
