It seems like I have a really strange problem. When I mouse-over blog entries or links in the navigation my browser shows what seems to be the correct permalink, but when I actually click on said entry, the URL in the address field of the browser doesn't change to show the correct URL for the permalink. However, when I open that link in a new tab, the URL will be shown perfectly fine.
URL of the blog is "myblog.com"
When I mouse-over the first entry my browser shows that the link will lead me to "myblog.com/?p=468".
I click on that entry and the URL in my browser just stays at "myblog.com" and doesn't switch to "myblog.com/?p=468".
When I open that entry in a new tab, the URL is correctly displayed as "myblog.com/?p=468".
I have absolutely no clue how to fix this error by myself.
