View source for Fatal error Class JClassLoader

==Errors reported==
If you try to move a website from a Linux based Host to a Windows based host or if you have a CentOS server you can run into the following error:

'''Fatal error: Class 'JClassLoader' not found in JROOT\libraries\cms.php on line 38'''

If you don't have a CentOS server or move your installation from Linux to Windows you actually don't have any known problems!

* On Windows (not case sensitive) that file gets replaced (all fine)
* On Linux (case sensitive) both files are still there and as the correct file is loaded in the code we only use the working file. (all fine)
* On CentOS you may get an error on updating that you have a name conflict.
* If you copy the files from the Linux Host to the Windows host it is possible the wrong file gets removed.
