No WYSIWYG editor (problem due to hosting ?)

[filmpl]

Hello,

I have several websites under GS (I love it !). The servers are hosted by a french company called OVH.

The problem I'm having with CKEditor looks like this one : http://get-simple.info/forums/showthread.php?tid=3466

Healthcheck is OK, I'm using PHP5.4, admin lang=fr, plugins disabled = still broken

As it appears on different sites (and different servers), I think this may be due to OVH, don't you ? Do you have any idea about where to look at ?

Thanks a lot for your help.
