Okay I did post something about this problem before but I've done more research now and I think I'm getting close to the root cause.
I can log in to my dashboard but I can't log in to my site. This used to be just in chrome and firefox but it seems that IE has lost the capability to circumvent it as well.
I noticed I had an error log and downloaded that.
It reads as follows
[19-Nov-2009 10:16:41] PHP Warning: require(./wp-blog-header.php) [function.require]: failed to open stream: No such file or directory in /home/xini/public_html/xhub/index.php on line 17

Now that doesn't mean much to me but having googled a lot people seemed to be pointing to the .htaccess file and permalinks. Now I don't have one of those files (I do for my forum so I doubt the server is hiding it), I am using a custom permalink structure though...
Anyway, I'm wondering if there's a problem with my installation. I installed wordpress in it's own folder called wordpressfiles, moved and altered the index file to the root folder and still no joy. The site works... it's just you can't log in on the actual site though all external links like livewriter work and you can post from the dashboard.
Anyone have any ideas?
