Error say just :
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
But i have nothing in the server log ???

and i have make the latest update from xenforo .
Rebuild not work same error .

That error is too vague, an ISE 500 can imply a lot of things. What is the actual error logged within your server's error logs?

Where can i found the log , Please .
In The Webseite Directory are no logs.

Something like this should be logged in your Apache error log (usually in a specific logs directory or within the Apache install directory), but I'm unsure if your VHost configuration will place a specific log elsewhere.
