Last week I changed my permalinks settings in Wordpress and since then half of my site has had 404 errors. I tried resetting the permalinks, deleting and rebuilding the pages with the 404 erros and repairing the database but neither has worked. I’ve been told from another help board for my wp theme support that the issue is probably a bad database and I need to reinstall wordpress. Does this sound right?
The article I saw on deleting wordpress shows that the database would remain intact unless I delete that too. If the database is the problem do i need to manually delete that and completely rebuild my site?! Is there anyway to save my site while reinstalling to fix a database problem?
I have limited general knowledge of wordpress and websites so please break it down kindergarten style for me.
