I am a JR to WP. I was adding posts to my site last evening and it was all fine. Then this morning (2010.02.23), I log-on an found few 'Posts edit' interfaces looked different. The 'publish' interface had password option, which I didn't have before. The 'Post Tags' interface became dialog box instead of single line entry. What affected me the most is all of the 'add media' buttons between title and content boxes are now disappeared. I didn't make any changes to WP except adding few posts. I didn't know how my WP 2.8.4 changed overnight, and couldn't bring back the 'add media' buttons/icons. Could someone help me to get those 'add media' buttons back? I have no clue on what happened, if somebody can shed some light on this problem would be greatful.
