Permalink mess

My blog was installed on website.com/blog (my blog is intergrated with my html website, I made my own template from scratch), but then I moved the blog to website.com/web. I changed the url in the admin panel, and the blog looks fine but I have some weird permalink issues.

I use custom permalinks like http://www.website.com/web/sample-post/

This worked when I was using the old /blog directory, but not anymore… all of a sudden, when I click on a post, I get sent to http://www.website.com/web/http:/www.website.com/web/sample-post/
Put my pages work fine.

I tried changing permalink settings back to default (?p=n), but posts still don’t work. I get sent to a blank page with only the comment field…

How do I fix the links to my posts?
And I also wonder if its possible to continue using the default ?p=n urls for posts, but use custom permalinks for pages only?
