I clicked the button to auto-upgrade the menu to v1.8.1, hoping it wouldn’t impact how things look/work in WP. I am using WP 2.7 and I did revise the CSS to display a different background image than the ones provided with the plugin. It was displaying fine until I clicked the upgrade button. While the CSS file hasn’t changed and still displays the code for the different image, the image does not display. Was there any change to the plugin that would result in this happening?
