HUB - Updating Theme (Manually)

Please check the auto-update article if possible. How to use Auto Update

Manual Update

You can download the latest version of the hub.zip at your downloads page, after downloading there are 2 ways of updating the theme manually:

Navigate to Appearance > Themes
Deactivate Hub by activating a default WordPress theme, such as; Twenty Fifteen, Twenty Seventeen. The reason for this action is to enable the deleting functionality - WordPress does not allow to delete the active theme.
Now you will be able to delete the Hub theme, by selecting the Theme Details and then clicking on Delete (Right Bottom Corner). This won't remove the previous theme options, so the information will not alter once you install the newest version.
Press Add New on this same page, then select Upload Theme, find the hub.zip file on your computer and click Install Now button.

Connect to your hosting via an FTP software
Unzip the hub.zip file on your computer
Upload the extracted Hub theme folder to wp-content/themes/hub, the theme will be updated by overwriting all the files of the previous version.
