Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/siparker/bbpress-vbulletin-permalink/archive/refs/heads/master.zipNo built-in updater. New versions won't appear under Dashboard → Updates. Install new releases yourself, or let Git Updater track the repository.
Attention!
You need manually flush rewrite rules after activating bbPress and this plugin. You can do it by visiting /wp-admin/options-permalink.php page. Or use wp cli (wp rewrite flush command).
