Did a search but it seems no one brought up this one before. It seems that the edit function do not work properly when I tried to edit my posts. Since editting opens the advanced editor, I'll group it under this thread. The following error occured:
1. Quote tag bug. Instead of normal tag [ quote ] [ / quote ] (sorry had to space it to prevent quote tag activation), it went into [ quote ] [ quote ] resulting in my editted post being nested in the quoted post i.e. double quote.
2. When the tag is manually rectified and the post is updated, it still shows the old post with the no. 1 bug as shown above.
3. Bug no. 1 above activates automatically i.e. [ quote ] [ quote ] in the editor when I tried to manually rectify again the resulting error under no. 2 above.
4. Quote tag bug only resolved when I used another tag i.e. italic but it took several tries before the post appears correctly.
