XF changed the edit parameter in the settings. So what used to be unlimited is now limited.
Is there not the tab with the 3 dots in the top right corner of the thread? It should be there and when you click on it there should be an option to "edit thread". If its not there I could edit it for you, PM me what you need done.Not to update a dead thread, but I am having the same problem. I'd like to update my Sale listing (https://risingsun4x4club.org/xf/threads/2000-toyota-land-cruiser-15-000-obo.30178/) but can't. Any suggestions or can a mod help me out if I send what I'd like to update it to?
