Updating themes can be done automatically using Envato Market Plugin (included in our recommended plugin list under Appearance > Install Plugins) and entering necessary data or manually by uploading ZIP file.
To update theme with a ZIP file just install it as usual (if using WordPress 5.5 or later). If you have older WordPress version then:
- Install/activate Easy Theme and Plugin Upgrades plugin
- Install the downloaded theme ZIP as usual
Notice: you won’t lose your site content after updating the theme, but for safer side you can take a backup of your site before updating the theme.
