I newly installed wordpress 3.5 to my blog General Blog 4 weeks before. All of things working fine.
But the some days before when I tried to log in i receive error message but I am able to log in.
When I write the new post i find the text editor style is changed and there is no option before i seeing like copy from word, font seleciton, make heading, sub heading etc.
The current text editor showing like "b" "i" "link" etc. I am very upset, try to resolve this but failed. Disable all the plugins but nothing to change.

Please help me to resolve this problem, why the text editor is changed & how i go back.
