I made sure to copy the files in place. Although I know I copied them there, I wrote over them again. Now I'm getting a Post error with the post.php file.

This is what I see when I submit a post:

Notice [PHP]: Undefined index: nosmiley in file modules/newbb/post.php line 166
Notice [PHP]: Undefined index: icon in file modules/newbb/post.php line 167
Notice [PHP]: Undefined index: attachsig in file modules/newbb/post.php line 168

I also see the "Thanks for submitting..." box above it, but I'm still not able to see any topic text. This is with the topics I converted over from PhpBB also. I see the topics, but I'm not able to read any of the posts.
