I'm fairly new at WP. I've installed a 2011 child theme at http://www.metacultura.org. I want the page to display at 1000px wide (like my other site at http://www.aguilateam.com/), but it comes up at 690 px, and the menu is wrapping to multiple lines. (Is this two problems, or one?)
The header image is exactly 1000x288. I've made only minor changes in the style.css file. I have installed no widgets, and the following plugins are active: Form Manager, Members Only, and Simple Login Log. The page default is set to one-column, no sidebars. All the pages are using the Showcase Template. I've turned off the custom menu. No help.
I have another site at http://www.integralview.org that is also using the 2011 theme and it, too, displays at 690px.
Where do I look to get the Metacultura site to format at 1000px, and stop the menu items from wrapping?
