Joomla Fatal error

[Arnol666]

Hi everyone!

I could use your help with this problem. First of all, i have no idea how to start but owkay, there she goes.

When i tried to install a new language for my joomla website http://www.chainedpistons.com/ the website totally crashed and i have no idea what to do.

This is the error i get:
Fatal error: JUser::getParam(): The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Joomla\Registry\Registry" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in /domains/chainedpistons.com/public_html/libraries/joomla/user/user.php on line 284

Please guys help me out, can i restore/repire this thing or not ?

There is no Joomla! accredited language pack for the language Slovene, especially for Joomla! 2.5 and Joomla! 3.

It is not clear which files you have downloaded (from the site referenced by you) and installed. If you provide the file names, at least others could test them.

well...here is the download link http://www.slojoomla.si/prenosi/slojoom ... -slojoomla

in the middle it says "prenosi", you just click that and u will get slovenian language pack. (prenosi = download)

Looks like this has been solved as the site displays fine.
In fact this is NOT a language pack but a full distribution...
