Wrong forum. But download the language packs from the download page and verify that they got installed correctly.

You could use Firebug to see that all files get loaded correctly. But since the language packs get merged with the english one it should always work.

It will load a table/langs/<lang code>_dlg.js file ones you open the dialog. It's loaded by the tinymce_popup.js file that is included by all dialogs.

Same exact problem here, too. All popups/plugin dialogs do not show human readable labels. The code works fine when we run it in a browser directly from a local file (without being served) but once we copy the files to our app/web server, the problem appears.

We've used Firebug to determine that the en.js files are being loaded -- the same set of files load locally or when served. In fact the HTML remains the same -- i.e. both the local page and the served page contain the exact same HTML and javascript references, e.g.:
<script type="text/javascript" src="js/tiny_mce/tiny_mce.js"></script>

In addition to using Firebug, we have verified that all of the TinyMCE .js files can be read (we type the path into the URL bar in the browser and the source appears).

Of course, clicking any [insert] button in any dialog produces a javascript error, e.g.:
insertAction is not defined:
onsubmit(submit )
or
ImageDialog is not defined:
onsubmit(submit )

Clearly, something isn't loading or initializing. But what????

Everything else in the editor seems to work -- it's only the popups associated with the plugins that don't work.

Please help!!

ok seekers of the labels, low and behold: I've found a dirty hack!!! :-D

uncomment and move a few lines in ....wp-includes/js/tinymce/tiny_mce_popup.js so it looks like this:

    requireLangPack : function() {
        var u = this.getWindowArg('plugin_url') || this.getWindowArg('theme_url');

        if (u && this.editor.settings.language) {
            u += '/langs/' + this.editor.settings.language + '_dlg.js';

//            alert("i came very far");

                tinymce.ScriptLoader.markDone(u);
//            if (!tinymce.ScriptLoader.isDone(u)) {

//      alert("now I'm inside this ScriptLoader check");

                document.write('<script type="text/javascript" src="' + tinymce._addVer(u) + '"></script>');
                tinymce.ScriptLoader.markDone(u);
//            }
        }
    },

that's as messed up as I could do!!

So basically (!tinymce.ScriptLoader.isDone(u)) never evaluated to true. On my own risk I set a markDone and then just go into the code inside the condition. Don't know the consequences, but now I got labels!

Hope that helped ....
