The following URL contains some vague instructions which I’m hoping someone understands a bit better than I do and can shed some light on for me: Omeka Classic - Locale Switcher
Usage
Install the plugin
Configure which languages you would like to appear in the language switcher
Put the following code in your theme files: <?php echo $this->localeSwitcher(); ?>
The part I’m not grasping is : What do you mean by ‘theme files’ ? I’m looking in my themes folders , and i see a folder there for each theme, but beyond that - am i adding code to config.ini, or index.php or theme.ini ? It’s not clear to me…
This said, to answer to your questions: by “theme files” developer meant the files you’d find in your specific theme directory (so: themes/whateverThemeYouAreUsing/etc.); wherever you add the code snippet (f.i.: items/browse.php), you’ll get the language switcher appearing.
