In case if automatic plugin installation fails (as a rule it is because of your server settings), you can install them manually via your Dashboard: Plugins > Add New > Upload Plugin > Browse plugins archives. Or via FTP, by uploading and extracting the plugin zip files into wp-content/plugins folder.
You can find the zip files for plugins installation here – https://www.8theme.com/download-plugins/
Please use this code for the WooZone plugin – m8xqWJ_8theme
Activation is not obligatory for all the other plugins.
