[TYPO3-german] Issue with menu

[Ronald Bouwens]

Hi everyone,

Since the hostingprovider migrated the webpages to a new server, we  
have several issues. The most striking is the fact that the menu on  
the page is 'covered'. Just take a look at www.brandweer- 
valkenburg.nl to see what I mean.

1. When you call the URL, you will see that the menu on the left  
shortly shows text, but this text is covered by a grey square.
2. In the template for this menu all the options are now switched off  
(no rollover, no backgroundcolor, nothing...).
3. When you move the mouse over the places where a menuitem should  
appear, you still can see the 'helptext' in the yellow flag.
4. Clicking on places where a menuitem should be, correctly links to  
the next page.
5. New pages created aren't shown in the menu either.
6. A testenvironment on the same server, in the same Typo3- 
environment works fine.
7. Pages copied from the 'live' environment to the 'textenvironment'  
are shown correctly.
8. Pages copied from the 'testenvironment' to the 'live' environment  
aren't shown in the menu either.

Who can show me the right direction? I suppose the template was  
goosed as the site was migrated to another server. Is this correct,  
and what's the way to resolve this?

Best regards,
Ronald Bouwens.
