Foren / Cotonti / Support / Mark it Up <<Halp>>

Hi folks..

the MarkitUp editor wont show on my site. All I see is a texterea. All bb code tags work though, even that of the bb_flow plugin..

Problem is that I never had this problem before, so I am honest when I say i do not have a clue on where and how to tackle this problem.

it is a fresh install of 0.6.17

with these (custom) plugins:

Autoalias2 (ver. 2.0.0)
Pageavatar (ver. 1.00)
Slimbox+ImageScale (ver.1.0)
Twitti (ver. 1.0)
tweetbutton (ver. 1.00)

Does any-one know a solution of a direction for me to search? thx..
