@Paul_Gibbs, the error I get is something like that:
[Thu Sep 22 08:47:40 2011] [error] [client 127.0.0.1] File does not exist: C:/wamp/www/wordpress/register, referer: http://localhost:9080/wordpress/
Thanks for your answer!
1) I did complete the install Wizard ( the one consisting of 6 steps, right? ).
2) I am on my own machine running Wamp ( Windows + AMP ). My site has a URL in a form http://localhost/wordpress in a web browser.
As for permalinks, I’m not quite sure what you mean. When I was asked for permalinks in the install Wizard, I checked “Year and month” option: year/month/sample-post. In the permalinks section of the Settings in the Dashboard I checked “Year and month” as well.
So what do you think? Maybe the fact I’m running BuddyPress locally causes such results?
