Hello, I am having an issue where I upgrade existing listings and/or create new listings and nothing happens. When I add a new listing, I put all the information in the "add a listing" and when I press submit.... the page thinks for a minute and then goes blank. The entry is NOT saved. If I try to edit an existing listing, I go to the edit section and make changes... press save and the page refreshes... but none of the changes are made. All of these changes are being made on the front end, with a username that has admin privileges.
