Missing editor buttons about meta-box HOT 6 CLOSED

Just checked the plugin with default TwentyEleven, no other plugins activated and it works normally. Can you please do the same check to make sure the problem doesn't come from the Meta Box plugin?

Oh, and please check if it is in the mark-up (see source code with dev bar, firebug, similar) and not hidden by some js or css.

Thanks both.
Normally I'm using the files from this plugin within another 'core functionality' plugin.
I'll let you know what actually happened.

Edit:

Weird.
Could one of you perhaps tell if there's something 'new' within this code which interferes with add_filter('user_can_richedit', create_function('', 'return false;'));?

This seems to be the cause of things.

Sorry, but anonymous and lambda functions can't really be debugged -> No chance to trace them down inside the global. IMHO that's bad practice as those functions are also not un-hook-able.

That filter disable rich edit at all. Try to delete that line and see if it works.

@franz-josef-kaiser you're right. I've updated my snippet to something a bit more valid :) Also, I should have been more clear when asking my original question, including I was disabling the rich editor.

Anyways, even though it wasn't especially targeted to this issue, it seems @rilwis last update solved things.
