After upgrading to WordPress 3.4.1 this morning and then WordPress SEO 1.24 I am getting the following error whenever I load any of my posts:
Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0
That's all. I know it's the WordPress SEO plugin because I disabled it and the problem is immediately resolved. I downloaded the development version to test and the problem persists.
I've left the plugin disabled for now but I can enable it at http://www.diagnosisms.com/ if necessary for testing.
