I’m having a similar problem. A fresh new install of v2.0 and accessing posts from the sidebar does not work.
I chose https://<site>/2006/01/27/sample-post/ for permalinks and the .htaccess file looks ejain’s, but RewriteRule . /blog/index.php is RewriteRule . /index.php.
Attempts to access:
https://<site>/category/<category>/ returns 404.
https://<site>/2006/01/ all fail, but returns 404
https://<site>/2006/03/15/<postname>/ works.
This is quite baffling. I’ve searched through all the support forums and it seems to me that there are quite a few errors of this nature being reported.
Things, like different things work or not depending on theme chosen, etc.
BTW, as another piece of information, if I choose Classic theme, instead of the Default theme, then archives work and the categories now return, “Sorry, no posts matched your criteria.”
Aaarrrgghhh!
Is it just configuration problems or is this symptomatic of an underlying problem.
