I am making a new theme at the momment, and everything works fine. In some random point of time ( i didnt change anyting important, maybe css and adding more functionality ) EVERY link of a post show the same article.
The URL may be diferent
localhost:8080/demosite/?p=302
localhost:8080/demosite/?p=12
localhost:8080/demosite/?p=85
Or anything, the printed article remains the same. If i delete this article, then some else keep showing on any link. I installed the theme on fresh install and it was working ok. (same code) After a little -> Same issue.
+ i cant change the permalinks settings, it always show error 404 page not found (from server, not my 404 page) if that matters.
