I have this issue with my vbulletin archive only, It has no pagerank at all around 1.5 years back we had a pagerank of 5 on main archive page: http://forums.techarena.in/archive/index.php/ and atleast PR4 on each forumpage of archive. http://forums.techarena.in/archive/index.php/f-17.html http://forums.techarena.in/archive/index.php/f-16.html http://forums.techarena.in/archive/index.php/f-24.html and lots of thread with pr2, pr3 etc. (archive threads are directly linked to showthread pages). But since last 1.5 years I have seen pagerank on this pages wiped off (gone) completely.. Although my forums/sub-forums are all having a PR of 2 or 3 each. As well many threads internally do have a PR.. What can be the issue here ?
