fresh Joomla! 2.5.14 and K2 v2.6.7 Installed below site

www.vgrov.com/k2/

But K2 not works on front end (Item/category) the linked page say "Server Error"

If we set error report to max its say

Strict Standards: Declaration of JParameter::loadSetupFile() should be compatible with JRegistry::loadSetupFile() in /home/vgrov/public_html/k2/libraries/joomla/html/parameter.php on line 512

Fatal error: Call to undefined function mb_internal_encoding() in /home/vgrov/public_html/k2/components/com_k2/helpers/route.php on line 67

Appreciate if any one could help to resolve

Does your server have multibytes enabled?

PHP Configuration Editor

Multibyte String	mbstring.detect_order	Auto
Multibyte String	mbstring.encoding_translation	Off
Multibyte String	mbstring.func_overload	0
Multibyte String	mbstring.http_input	Auto
Multibyte String	mbstring.http_output	SJIS
Multibyte String	mbstring.internal_encoding	EUC-JP
Multibyte String	mbstring.language	Japanese
Multibyte String	mbstring.substitute_character	none

Need any changes?

I would probably double check these settings with my hosting provider, since I am not a sysAdmin. You can always check the mbstring.language = Neutral setting.

Dear Krikor,
Your info is worth for us.
We re-compile apache with mbstring
