How to upload a new WordPress Theme?
If you would like a new WordPress theme for your blog web site, first of all you will have to download it to your local machine. You can visit our Wordpress themes gallery and download free themes from there:
Once you have the new Wordpress theme on your local hard drive, you have to upload it under the 'wp-content/themes' directory of your website. You have two options to do that:
- You can upload the .zip file of the theme in the 'wp-content/themes' directory via the File Manager and extract it online, or
- Extract the file in your computer and then to upload the content in the desired folder via FTP.
Now, that you have the new theme uploaded on your site in the right folder, you can see it in your WP admin panel and select it as a default theme for your site.
