@chris Olbekson – perfect! Disabling that fixed it for me 🙂 Thank you for your help!
I am having this issue as well. I looked at other threads, and saw that people had luck disabling plugins or changing themes, but neither of those options worked when I tried.
For reference, my blog is at http://charity.stephonee.com
And the themes I tried were:
http://wordpress.org/extend/themes/beach
http://theme.wordpress.com/themes/twentytwelve/
http://wordpress.org/extend/themes/next-saturday
Are you saying that you the parameter actually changes back to summary in the option screen? If so, I’m not sure what would be causing that, sorry.
Yep, that’s exactly what’s happening. I don’t use the “more” tags in my posts, so I know it’s not that.
