database problem, non-funcioning categories, or permalinks

ok. i have searched the forums and i can’t find what i’m looking for. could someone have a look at this and tell me what’s wrong – https://www.benwoodward.net

if you click on post titles it just loads all the posts, as does categories and archives.

i am no coder, but i am aware that it could be something to do with .htaccess file?

i think the server is apache, but i’m not sure what version.

are there any servers that set up wordpress for you so i don’t have to deal with all these tech issues?

many thanks
ben.
