What happened to the options in making a post

[bhast2]

when you use to make a post here you could upload a file
you could make it html,txt,or BB (i think)

all of the options are gone now when you make a post

and i have this error on top of my web browers
include($Configuration['EXTENSIONS_PATH']."Mootools/appendix.php"); include($Configuration['EXTENSIONS_PATH']."Mootools/default.php");
