Can Anyone Explain How to Install A Wordpress Theme on Cyberpanel ?

Hi all, I just moved over from Siteground to Vultr with cyberpanel installed. I have installed wordpress but cannot install theme. I try to upload theme and i keep getting the following message -

403 Forbidden Access to this resource on the server is denied!

can anyone help or post a link that can show me?

Thanks

Hopefully I’m wrong but it just sounds like a permission problem.

Access your website management panel.Open File Manager.Enter the public_html folder.Delete the currently available default index.html template file.Go back to the main menu.Click the WordPress icon in the Application Installer section. This will lead you to the installation wizard of WordPress plugin.Fill in all necessary details including Blog Title, User, Password, and email.Now click the blue “Install Now” button.Wait for the installation process to complete.Once done, click GO Back.That's it.

It must be a permission issue, it should be 755 for folders (changing this to 775 might help) and 644 for files ( 664 to solve some issues).
Also, check wp-config, not sure if this is your case but worth a shot, add this line:

I had to FTP the folder instead of the usual way through wordpress site. Job done.
