I have tried that, changed it to every option, same result. Have tried most things like that. Changing permalinks, changing htaccess etc etc. Have literally no idea where to go next!
Actually, just to add this. Before, when I added the index.php into the link in the browser, it directed me to the right page. Over the last few days, I’ve done some jigging around with solutions I have found on the net, including stuff like adding a .htaccess file and a PHP bit of code here and there (I take them afterwards out if they dont work) but now for some reason when I add the index.php it just returns me to the homepage each time, so something has changed. It still does this even after I delete the .htaccess file.
