[SOLVED] Error: Unknown Language

[joeck]

Hey there,

I'm very new to Processwire but allready in love!

So far my experience was great but I ran into an internal server Error (500) and my error logfile logged:

Error:     Exception: Unknown language (in P:\xampp\htdocs\xxx\wire\modules\LanguageSupport\Languages.php line 343)

(I know XAMPP is not the best developing area but for simplicity reasons I like it...)

The line 343 in my Languages.php(unchanged by me) is:

if(!$language instanceof Language || !$language->id) throw new WireException("Unknown language");

in the function of 

public function setLanguage($language) {
		if(is_int($language)) {
			$language = $this->get($language);
		} else if(is_string($language)) {
			$language = $this->get($this->wire('sanitizer')->pageNameUTF8($language));	
		} 
		if(!$language instanceof Language || !$language->id) throw new WireException("Unknown language");
		$user = $this->wire('user');
		$this->savedLanguage2 = null;
		if($user->language && $user->language->id) {
			if($language->id == $user->language->id) return false; // no change necessary
			$this->savedLanguage2 = $user->language;
		}
		$user->language = $language;
		return true;
	}

I have no clue what the problem is and as far as I know when I closed the website the day before everything was working just fine.

I copied the whole folder to "develop" further on my laptop.

The next day I got the error mentioned above when requesting the site. (On the original and the copy)

Any suggestions what I should do?

Well I finally figured out my problem...

I set the language on top of my document to German (Deutsch):

$languages->setLanguage('deutsch');

and after that changed the names  of my languages which is why it threw the errror...

consider this topic as fixed/closed. I don't know how to mark the topic as "solved".

Cheers
