Hello,
I found a strange behaviour of Ribbonbar control panel: it only shows the "copy page" button when you're using portal default language, with any other language it is hidden.

This is due to this line of code from admin\controlpanel\RibbonBar.ascx.cs:

copyPageButton.Visible = LocaleController.Instance.IsDefaultLanguage(LocaleController.Instance.GetCurrentLocale(PortalSettings.PortalId).Code);

My question is: what's the reason for this? What could be the risk of enabling such function with other languages?

Regards,
al.

 Sebastian,
thanks for your answer. The "master language" concept is not entirely clear to me: I understand DNN's default language (master language?) affects what you can and cannot do (e.g. copy page), but miss something. If I go to Admin > Languages and click to Edit culture (first edit button, before the three for static resources) I see:

• I can set translators permissions for NON-default language
• I cannot set any permission for the default language (can only set fallback language)

Why aren't we allowed to set permissions for the default language too?
I must say all of my localized sites use ML modules and a single navigation tree, that is I never used DNN's built-in localization capabilities (which force you to have different navigation paths for each language), so maybe my approach is different. 

Also, if I'm not missing something, I know any tab has a default language (culture) associated to it into the db, but this is not shown on page settings - is this used only when content localization is enabled?

Thank you,
al.

 Yep I normally use EALO as localization engine, working pretty well.

Thanks for the suggestion: I installed this control panel and am asking customer to try it, even if I don't think it really solves his problem. With this new control panel the "duplicate page" button is actually enabled for any language, but if you use it while not under the default language you'll have limited capability to duplicate the page - no modules are shown under the "Copy Page" tab.

I wonder if this core behaviour could be adapted: if core localization is disabled I'd want full control, but I have not even if I'm a host user.

Another doubt I have is about the way copying modules from other pages is allowed: I always can choose to make a New module or to keep a Reference to the original one, but the Copy option is always disabled. Well actually not always: I saw it enabled somethimes, but was not able to understand why and when it is enabled. Does this depend on the module type?

al.
