I'm having several issues with Sandbox theme displays. These are all cropping up in a brand spankin' new install - the only change I made to the fresh installation was to add Sandbox and import some entries to test the design display.
First, the default, fresh-install display is only displaying the main column in the appropriate width for a post or two, then the remainder of the posts are displaying at 100% width.
Second, on the diurnal set (for example), I tried to go in and clear the float-left property and set a fixed display width for the container... and in addition to the problem above, then the 2nd and 3rd (secondary) columns then displayed at the bottom or off-screen altogether, rather than displaying at the top as designed. (similar to this problem).
I'm a loss at what to do or how to fix it.
I can't seem to get the default themes (Boston skyline, Unity, etc.) to display properly, either - they're all shoving the sidebar content down at the bottom of the page as well. Any help or guidance you can give would be much appreciated!
