AFAIK It works fine, so much so this very support forum is using it:
On this wordpress.org/support site is running the following versions:
WordPress v6.4-alpha-56396 & bbPress v2.7.0-alpha-2
(The above versions are very similar to 6.3 & 2.6 with no discernible changes)
Steps to Reproduce Issue
- Install WordPress 6.3 (via Scriptaculous)
- Login to WordPress, install, and activate bbPress plugin
- Create a Forum
- Try to open that forum
Expected behavior: forum loads
Actual behavior: blank white page
Testing: Turned on WP_DEBUG, WP_DEBUG_DISPLAY, PHP show errors in wp-config and still blank white page with no further debug output.
