@MF-Warburg: Unfortunately, I used visual editing, which doesn't work. So, I tried to convert it into source editing but there's always error message displayed whenever I press the edit button (pencil signed one). So, how shall I recover my source editing format without pressing the edit button (pencil sign) ? Haoreima (ꯉꯥꯡꯐꯃ) ꯱꯵:꯲꯶, ꯲꯶ ꯐꯥꯏꯂꯦꯜ ꯲꯰꯲꯱ (IST)
Oh it's ok, when I press edit button in your user page, there came no error message. So, through your user page, I changed the source editing from visual one. By the way, one thing I missed to ask you.
