I changed my blog theme to "Twenty Eleven 1.2" after upgrading the blog a few months back.
The problem that I notice is that I keep on getting "page not found" error very often (For example: When I tried to login http://michaelsync.net/wp-admin/ then I got "Page not found" error ) I need to refresh two or three time to get it working..
Is this the known issue?
I'm worrying that there might be some plugins or themes that interrupt the http-request/response route to make my blog slower ...
I also get this error "An automated WordPress update has failed to complete - please attempt the update again now." but when I click on "attempt the update again" link then it said my blog is up-to-date already.. It's very weird.
