Where is generated the space (aqui aparece el espacio) 


And here a section of the forum used the code:

Thanks!

If you are using WYSIWYG mode, it will add a space.  If you are not, it will also add a space.  You will need to move the line right after the ending tag:  [/code]Line.

So.. are you saying is a problem with FM? Because I have a test site and there does not happens this.. and well, it does not matter if I put it after the close of the code.. it stills generating a space after edit it. It is really annoying. >.<

I don't think it is necessarily a problem with FM, more so the way the editor was coded.

-solved- thanks
