Why this matters
By default, Safari opens "safe" files after downloading — which includes unzipping .zip archives. If you're downloading a WordPress plugin like Linkilo, this gets in the way:
- The zip turns into an unzipped folder
- WordPress's plugin uploader expects a
.zip, not a folder - You end up with errors like
PCLZIP_ERR_BAD_FORMAT (-10)
How to disable auto-unzip
- Open Safari
- Safari → Preferences (or Settings on newer macOS)
- Open the General tab
- Uncheck "Open 'safe' files after downloading"
From now on, Safari leaves your downloads as-is — you decide what to do with them.
What if Safari already unzipped your plugin?
If you've already downloaded Linkilo and Safari unzipped it:
- The unzipped folder is still useful — you can FTP it directly into
/wp-content/plugins/ - Or right-click the folder → Compress → you'll get a fresh
.zipto upload via WordPress
Or just re-download from your Linkilo account with the new Safari setting in place.
