Go button disappears when trying to post an ad, then clicking the back button
This is similar to the Solved solution however I have categories with one category with a subcategory. When you select a cat without a sub category and click "go" it will bring up the ad listing form. If you then click the back button it goes back the category selection and will not display a go button from that point on until you refresh the page. This does not happen when you use the category with a subcategory item.
For some reason I have several users doing this.
