Hello there
I recently upgraded my WordPress from  3.5 to 3.5.1 and now I just noticed that I am unable to edit any posts. Every time I try editing  a post I get 404 error. I tried to reinstall 3.5.1 but I got the bellow error:
Download failed.: Couldn't resolve host ''
Installation Failed
Can anyone please help me fix this?
Your support will be highly appreciated

Check your plugin and deactivate all of them and see if this fixes the issue. Then you can start activating them until you find the problematic one, which you would have to look for an alternative to it.
