I've integrated wordpress into my website and changed the appearance of the twentyten theme to match the website:
http://www.brummiebiker.co.uk/blog (be aware it is still under construction). Everything seems to work fine except the displaying of any of the archive pages eg - http://www.brummiebiker.co.uk/blog/2012/03/
This type of page seems to be using an old version of the HTML patch and thus the CCS class names are wrong.
I've looked at all the PHP files on my system and can't find one that is using the old HTML.
The single page "sample page" displays correctly. What file should I be editing to correct this issue?
