first excuse for my bad english.
i have tested some blogs like b2evolution, plog, bBlog and serendipty with XAMPP [http://www.apachefriends.org/en/xampp.html]
to my mind serendipity is the best blog. after the local testing install i decided to install it on the webserver.
the installation made no annoyance. after the installation i get a "internal server error"
only when i deleted the ".htaccess" from the webserver, it is possible for me to enter the blog.
My web server was doing this a little while ago--check your apache error log. Mine was emitting a 500 because a certain file (maybe .htaccess, don't remember) was world-writeable. If that's the case, just use an FTP client to change the permissions on the file after it has been created.
