I wanted to change my permalink structure from http://example.com/?p=N to http://example.com/category/post-name/.
So I changed the structure in my settings to /%category%/%postname%/.
After I saved my changes the blog doesn’t work. 🙁 I can’t access my website and I can’t even access wp-login.php anymore so I can’t change it back.
I hope someone can help and tell my why the problem occured and how to reset it. Thanks.
