How can I backup my entire wpforo forum,
I wanna move everything on my forum to another site including the content, users, customization, themes, everything
More like a duplicate site.
There is no way to do that separately. You should clone the whole WordPress and delete non-wpforo content to get a duplicated forum.
@robert how about downloading the wpforo plugin folder from the old site using cpanel and re-uploadinig on the new site 🤔
The folder contains nothing. It's just the plugin files wich can be re-installed on your next WP.
You should care about the database data and the wpForo files in /wp-content/uploads/wpforo/ directory. The database data are stored in wpforo tables, in wp_options table, in wp_posts, wp_postmeta tables, in wp_users and wp_usermeta tables. In other words, the database data are mixed with WP data, you can not separate them easily.
