Hi,
It seems that the problem comes from your Joomla template. Try to temporarily switch to the default template of Joomla to check if you have the problem. If you don't, I would recommend to contact your template provider for further help on that issue.
We moved your thread into the German forum section ; please use that forum for your messages in that language.
Otherwise, please use English for your messages.

By the way, do not send me private message, use the "contact us" form instead.
