[Plugin: WordPress Category Archive] Not showing all archives

Hi,

plugin works fine but it doesnt show all of the posts.
It shows (now) only post up to last october and nothing before that.
I even tried with posting a new post and it came up fine, but when I edited its publish date to last june, it didnt show on archive.

Is there some setting on the code or is my websites settings somewhere wrong? Please help me 🙂
