If you are having trouble with functions in the ZOO, this might be due to a jQuery conflict. Please read this tutorial on how to detect and resolve the problem.
Unstyled content - no CSS being loaded
This might be due to file permission issues. Please read this tutorial on how to detect and resolve the problem.
This is most likely due to a php error being thrown. Please enable the display_errors parameter in your php.ini. Only with an error message the problem can be found.
Another way to check for PHP errors, is to have a look at your PHP error log. The PHP log shows information on errors and warnings thrown by PHP. Your host should have configured PHP to write that information to a log rather than output them on screen.
