Question Error after installing Language Pack german?

hello everybody...

i habe installed kunena today the first time.
my basic system ist joomla 1.5.9, also the stable reelease with german language packs.

installing kunena was successful, i changed and copied only the images folder because there was no permission to creat ot.

after installing kunena i want to change the language to german so i downloaded the files from here.

also installing was successful too, but opening the board and changing to "Profil" i am getting the following message:

Fatal error: Call to undefined function changedate() in /is/htdocs/domain.de/www/subdomain/components/com_kunena/template/default/plugin/myprofile/myprofile_summary.php on line 77

google could not say anything about, so please help me.

thanks... ck

Please override the modified files with the two files in attachment (that are the original files fo Kunena 1.08). There are existing a few bugs with the dateformat coded by xillbit, but these errors exist not on every installation. Xillibit is testing to find a solution, that works on every installation.

Perhaps you could try the newest one here including 3 files. (Please backup the summrry.php before testing to put back after a failed test, because this file is not in the attachment).
