When I'm using dynamic locale to change site language, at every instance of gettext_th script shows following error:

Warning: Cannot modify header information - headers already sent by (output started at ........../zp-core/template-functions.php:4186) in ........../zp-core/functions.php on line 1599

What is it?

Can you tell us please what version of Zenphoto, etc. So we have the data needed to help you.

Zenphoto 1.4.0.1, live example here: http://ab.maglan.ru/magadan360/ (language selector at bottom).

I'm using gettext_th('string') for all theme strings, /locale/ru_RU/magadan360.po and poedit as described in manual. The gettext('string') working fine.

Are there .mo and .po files for zenphoto in the ru_RU folder?

Best guess as to what is happening is that Zenphoto is getting a failure trying to restotore the locale settings after the gettext_th call.

Yes, both .mo and .po files are in ru_RU folder.

You do really have separate theme translation files as well?

Sure. And it works fine all the time. I get errors only when using dynamic_locale to switch language.

I have placed a change in the nightly build for 2/16/2011. Please try this and see if the problem is fixed.

Everything is OK now. Thank you.

Hello again.

After some upgrades on my hoster's server function gettext_th is not working anymore. No matter what languase is set, it shows english all the time.

I have checked .po files, all OK. On local server everything is working fine.

You can check it on magadan360.ru.
