Well, it means exactly what it says. If you are lucky, you may find further 
information about this error in the wiki.

All exceptions in the core have a unique exception number (the UNIX 
timestamp at writing the exception).
This is used to generate a unique link to the wiki.

The nature of a wiki, especially mediawiki like used for wiki.typo3.org and 
wikipedia is that you can a unique page per URL and you can enter 
information at any URL even if the page does not yet exist.

Go ahead and fill it if you have a solution for an exception.

So what is your problem. TYPO3 detects that you are trying to call something 
inside a plugin folder that does not exits.

That happens if you install an extension and then remove it on the server 
without uninstalling it inside the extension manager.

Just remove the extension key inside LocalConfiguration.php

So go ahead and import it into your installation.

1. it is an error (an exception) due to a misconfiguration from you
2. it is a wiki, so you can edit the text if you can provide some details 
for others that might get an exception, so that they do not have to ask 
again
3. you can edit it via the edit link that appears if you login
4. It is not a bugtracker, but wiki, so do not edit details of your error, 
but the solution to solve the misconfiguration

> What should be the difference between this WIKI and the bugtracker?
see 4.

If you want those pages to contain more than a sample text, then go ahead 
and full it with the information I gave you above.

Funny that you have to ask about an error you should have seen in the years 
of working with TYPO3.
