Forum-Links in extend and other run fail

[hempelr]

do you have an example of one not working?

They seem to be working fine for me.

The Link on the Site Extend -> i18n-Gallery - Link
http://get-simple.info/forum/topic/1882/i18n-gallery/
there comes nothing, and if I search in the forum then the url in the browser-adress-field is as follows:
http://get-simple.info/forums/showthread...8n+gallery
If I click on the links on the extend-site or that in the forum-articles then I get a only a white page...
