尋日哩個問題搞咗我一個下午….都未搞定，今天終於搞定嗮！

個方法就係：

1. Unchecking the forums component in the BuddyPress Component settings page.
2. Renaming bb-config.php in your WordPress installation root directory to something else (making BuddyPress believe that bbPress is not installed).
3. Re-checking the forums component in the BuddyPress Component settings page.
4. Re-installing the group forum component in the BuddyPress Settings “Forum” tab.

未免有D同學睇唔明，我翻成中文先：

進入到控製麵板 – Buddypress – components （組件）

1. 取消選擇
   

   Discussion Forums	Full-powered discussion forums built directly into groups allow for more conventional in-depth conversations. NOTE: This will require an extra (but easy) setup step.

2. 重命名您server根目錄的 bb-config.php，例如bb-config_stop.php (主要係讓BuddyPress認為 bbPress仲未安裝).
3. 重新勾選上1點提到的選項
4. 進入到forums (論壇) ，重新安裝埋新唧Group Forums

 

就係咁喇！
