ok, so i'm running the latest WP version (1.5.1) and i experienced the following problem with the "posts_nav_link" feature:
the wordpress address is: thelastbeat.com/blog
the blog address is: thelastbeat.com
now when i open my page the first time and try to click on the "previous entries" link, i get a 404 error, because it wants to access /thelastbeat.com/blog/page/2/.
when i enter the admin panel, and view my blog after that (same browser window), the link becomes /thelastbeat.com/page/2/, and it is working.
so obviously it is using the wordpress address first instead of the blog address.
i haven't found a solution so far in here. someone said that it is a bug in 1.5, but i'm running 1.5.1 and getting this problem....is there a way of entering the correct address somewhere manually?
thanks in advance.
