First of all, you need the plugin package as a ZIP file. You can download your purchased plugins on themezee.com/downloads/. Please be aware that the downloaded file is already a ready-to-use ZIP file, which you can use right away to upload to your WordPress Dashboard.
Please note: Some browsers like Safari include an automatic extract feature, which will unzip the.ZIP file when you download it.
Therefore you have to deactivate this feature before you download the plugin. Now, click a ‘Download‘ button in which item you want to download.
