Forum:Cannot open editing page

I actually have a problem with my own wiki. Since several hours, when I try to edit a article, I get a message 'loading editor...' and this continue to appear permanently and nothing happens. Firstly I thought it would be an network problem, but despite I can edit on the other wiki (just like here) and according to editing log, the other users don't have this problem with this wiki. I don't figure out what's going wrong... I sent a report mail to wikia but I would also like to ask here. Thank you for any advise.
