Yesterday I moved my blog to a new server. After this migration I faced the problem that the wordpress navigation was broken. It always redirected me to the loginpage and I could’t navigate in the posts.

After reading some troubleshootings I found out that it could help to find a broken plugin. So i deactivated all plugins and then my navigation was working fine. After reactivating each plugin one after another I found out that Polylang was broken…

So I went to the settings-page of Polylang. On this page the plugin told me that not all posts have a language definied. So I let Polylang correct it by itself. After this I opened all languages and saved them again.

In my case this was all I had to do and the navigation in my blog is now working as before. Hope this can help anyone…
