If it could help to anyone.
The problems came from some statistics option I enabled on my server side. They were “puting” some script everywhere.
I disabled it and since all is working perfectly.
some update : I tried to install the 2.9.1 version of wordpress on different directories of my website, still blank page after 2 seconds after install.
But if I desactivate javascript, there is no problem.
So it looks like a javascript problem
Any idea about how to fix that?
I have the same problem, and even more…
A lot of things are not working well actually. Not only the widgets. Sometimes I get a blank page for no reason.
The Dashboard page stays for 2 seconds and then blank page…
The visitor side of the blog is kind of having some problem too. There is a slideshow and now for 1 or 2 seconds you can see all pictures.
I tried all possible fix.
I installed a new wordpress on the same “website”, and I have a blank page straight after the login.
The thing is that it happened like that.
