When i click your older posts specific link as well as archives for (October 2008 and November 2008) working very well for me. DON.
figured it out... your older post link is like http://technology.webwritinggroup.com/index.php/index.php/page/2 change the blog URL in your dashboard to http://technology.webwritinggroup.com
There is some database connection error. Check your database and config.php file and cross verify your database name, User ID and password over there. Let me know if still getting same error.
Yes i hav checked..all are okay.. i hav changed permalink structure to /index.php/%postname%/ after that i am facing that problem. i dont want to use any other permalink. where shud i do changes and what changes to get older posts working?
Why in the world you would want to use this structure? adding index.php to the permalink serves no purpose and provides no benefit. /%category%/%postname%/ is what I would recommend or just do the /%postname%/ - update options in Admin->Settings->Permalinks You might have to manually edit your .htaccess file as what I see on your blog is not properly formed permalink structure or perhaps messed up rewrite rules.
