I was working with the main menu of my site and moved it from sidebar 1 to the features panel and used css code to format it horizontally. I tried to get the second-level menus to appear in the sidebar, but it didn't look right. I put the main menu back in sidebar and deleted the css code. The menu is still formatted horizontally and the level 2 menus are displaying, when they weren't before unless they were clicked on.
I tried clearing the cache on Firefox, logging out and back in and using a different browser (IE) but the menu is still displaying horizontally with level two menus.
Has anyone come across this and know how I can fix it?
