The problem with the Russian localization, in place of the month shows in Russian characters, using topic zenpage, see what it looks like you can on the link - http://zenphoto.orthodox.ru/zenphoto/page/search/archive/2010-10
Thank you in advance, with respect for Alexander.

Looks like Chinese characters... does it show that way for just the Zenpage theme or all themes?

Yes all topics hieroglyphs version-zenphoto-1.3, here are the results of the script - list_locales

What could be the problem?

Date "translations" are all done by PHP, so be sure you have that configured correctly. If I recall correctly, this is involving mbstrings, but check setup for what it reports.

When installing, mbstring is written -
mbstring package [Your internal character set is EUC-JP]
Warning!
Setting mbstring.internal_encoding to UTF-8 in your php.ini file is recommended to insure accented and multi-byte characters function properly.
I understand that the need to change something in php.ini?

No double posts please. You already did post that 11 hours ago.

And to your question, yes, or contact your host.

Yes, you need to edit your php.ini file and change the item as described in the warning. Because your internal strings are Japanese you are getting Kangi dates. If you need help in changing this setting, contact your service provider.

Is it possible to change mbstring.internal_encoding through. Htaccess, if possible, how?

Yes, if your server allows that

Thanks for your support, all corrected through. Htaccess!
