Okay. I must say upgrading to 3.2 has been the worst thing I could have ever done. :( I've been working hours to fix this. Still to no avail.
Every site that I have upgraded now has a "Flash Of Unstyled Content" on every single page load.
So I ended up not only uninstalling every single plugin but I deleted them as well. That didn't work.
So next I deleted the custom theme and activated Twenty Eleven.
Still a "White Flash" on every single page.
Then I went into my profile and unchecked "Show Admin Bar when viewing site." This actually solved the problem of "White Flashes" in Twenty Eleven Theme.
So I thought I had solved the problem. Then I reactivate my theme and the "White Flashes" are back.
I've also tried the plugins, Auto Optimize, Scripts To Footer and Wp-SuperCache to no avail.
30 of my sites using WP 3.1 are still just fine. No FOUC or any problems what so ever.
But EVERY SINGLE site that has been upgraded has problems.
Does anyone have a working solution for this?
Do I have to delete my site and manually reinstall WP 3.1?
This is a nightmare. It's seems 3.2 was so where near ready for release.
Please someone help. I'm dying here.
PS. Please don't close this thread until there is actually a working solution. I see a ton of closed threads on this subject with no solution.
