I have a postcode showing, which isn't now applicable and for the life of me, I can't find how to change it. I have searched on Gumtree support and the answer comes up saying your location is at the top left of every page.....well it isn't! Any ideas anyone?
If on a desktop: Sign in. On the top right hand side click on 'My Gumtree' and go to 'Profile'. Scroll all the way to the bottom to your contact details and change the address to what you would displayed on the homepage and click the save button beneath it. Mine had the correct location (different to what was displaying on the homepage) but after doing this it now shows my local area as the default. Hope this helps.
