pegasus, i am sorry, just found out another problem, maybe related with above :
Cant renaming/edit Title
in edit page >> Title >> i change the title, and check list 'Do not create a redirect when renaming this page' option
after that i redirected to new page, but the content just this :
There is currently no text in this page.
nb.
- i already tried not to check list 'Do not create a redirect when renaming this page' option, but the result still same
- there is no problem if i just edit the article content, only got problem when edit the title, cant edit title right now.
Please give hotfix too if you can, Let me know if you need try live forum and login details
