Language changes suddenly

MarkusDippold

Hi,

from one second to the next, the admin-panel and the user-panel change their languages to english.
I have no idea, what has happend.

Changing the language in the options-folder in the admin-panel seems to have an effect only to the name of the month, that is shown in the gallery. All texts of mouse-over, titles, buttons is in english.

In moment the language-option is set to "http accept language".
Link to the gallery: http://modellbahn.dippold.org/

Have anyone an idea, what to do?

Regards,
Markus

With HTTP accept language set, the language selection will be based on what the browser says is the prefered language. If no prefered language translation exists then Zenphoto will select English.

please see http://www.zenphoto.org/2009/03/troubleshooting-zenphoto/#3 for a script which might help you figure out what is happening.

Hi,

the result of list_locales.php is this:

But the prefered language of my browser is german.
Setting the language in the option-folder if ZenPhoto to german, the texts are still in english.
Setting the language in the option-folder to french, the texts are still in english.
Setting the language in the option-folder to polish, the texts are still in english.
Only the name of the months changes the language.

I'm uploading in moment the locales-directory. Maybe this will work.

Markus

Copying the files doesn't work.
So I do a little trick: I copied the LC_MESSAGES-directory from de_DE to en_US.

The en_US-directory was empty before except the file select_files_button.png .

You can try setting the `DEBUG_LOCALE` define to true in function-i18n.php. This will log the language selection process into the debug log. Also, were there any warnings from setup.php?

"Also, were there any warnings from setup.php?"
No, the gallery worked fine during the last few weeks.

Last sunday all texts are in german. I've uploaded a new picture, all texts are still in german. I clicked through the gallery, all texts are in ... german.
I clicked to the next picture: All texts are in english.
Seems to be a little bit strange.

Yesterday I have tested, if gettext() is available with my hoster. It is.
The if-conditions is NOT called, so the dummy-function of the gettext.inc will be not used. To be absolutly sure, I added to the return-string a few letters. The dummy-function in gettext.inc is definitely not used.

As I wrote above, I copied the Messages-directory from de_de to en_us. This is a workaround for me. I don't expect a lot of foreign visitors to my gallery. All my descriptions are in german also.

Today in the evening, I will set the DEBUG_LOCALE.

Regards,
Markus

MarkusDippold

Ok, I deleted the message-directory en_US, so the original state for this is established.

This ist the output. I changed the language from English (not traced here) to HTTP Accept Language to German to French to English. The texts are always shown in english.

For me, this looks fine.
I have uploaded the locales-directories yesterday. This should be ok.

I do not know why it is not working. The trace shows that it is finding the correct HTTP accept language and setting locale to it. So I guess there is a problem with setting the locale on your server.

itaymesh

I not sure if it related to the problem above, but I also used dynamic locale plugin (which great) and the languages also switched suddenly.
I tested it some more (especially in IE 7 & 8) and found out that there a cache problem: the browser loads the page with the language that been used must recently.
I had to disable browser caching (which is not so good I think) in zenphoto index.php page (at root directory):
---------------------------------------------------------------------------------
/**
* Invoke the controller to handle requests
*/
require_once(dirname(__FILE__). "/".ZENFOLDER.'/controller.php');

header ('Content-Type: text/html; charset=' . getOption('charset'));

// disable browser caching so dynamic locale will function properly
header( "Cache-Control: no-cache, must-revalidate" );
header( "Expires: Mon, 20 Dec 1998 01:00:00 GMT" );
header( "Pragma: no-cache" );

------------------------------------------------------------

I will try to find a more optimized solution for this problem.

Any suggestions meanwhile?

itaymesh

by the way sorry about the bad English. I the post quickly

sbillard

I know that IE8 does seem to be overly agressive in retaining cache pages. I can change CSS files and not get IE to render the changes whereas FF will notice the change and do things correctly.

acrylian

You probably could also use our html_meta_tags plugin to disable the browser caching.

mikeque

I am experiencing something somewhat similar. I am working on a multi-language website that allows the user to switch between English and Spanish. Switching the language works on accessing the pulldown, but doesn't stick. As soon as I navigate to another page, the language selection is lost.

In trying to isolate the problem, I even tried create a new database from the setup page and switched to the default theme, and the problem persists. I regressed the installation to 1.2.9, and the problem goes away. Could there be something in the 1.3 release causing this?

sbillard

Well, the language setting should be remembered by a cookie. I do not think that changed from 1.2.9 to 1.3, but of coures it is possible that something has impacted it.

At any rate, there is a define, `DEBUG_LOCALE`, in functions-i18n that if you set to true will record all sorts of information on how the language selection is being made.

sbillard

I did find the problem. Somehow the saving of the language to a cookie was lost. That is restored in tonight's build. For the adventurous, the change is isolated to the functions-i18n.php script. That script may be used to replace the one that is included with the 1.3.0 release with no problems.

mikeque

great! thanks
