I do not speak German and unfortunately google does not translate a logged in page.
I have installed the captcha and am having issues with it not showing on the registration page in FireFox. This only happens after it has shown once and the page is refreshed. Then it disappears. I have read the forum and noticed that you have solved this problems many times, sadly the fix is not findable. I could use some help with understanding what I do not have done correctly.
