[Plugin: Polylang] Language switcher in custom place in template

The function exists and that’s strange that it does not work called from a template file. Such error will occur, of course, if the function is used before Polylang is loaded. In which file did you put the line?

I want to have the switcher to the header so I called it in the header.php file.

When does Polylang is loaded?

Polylang is loaded by WordPress as other plugins so much before the template files are loaded. Have you a link to your site?

My wordpress is locally installed so I cannot give you any URL’s

But to be specific I tried to load the function in the header.php file in the twentyeleven template, just after the search bar.

And I got the error I pasted above.

I will try to load it to the index.php and see what is going on.

Thanks for your answer I will report back soon.

Works perfect for me like this in the header.php of Twenty Eleven:

...
			<?php
				else :
			?>
				<?php get_search_form(); ?>
			<?php endif; ?>
			<?php pll_the_languages(); ?>
			<nav id="access" role="navigation">
...

Ok I have found the error…

I copied and pasted the code from the documentation and an invisible character was inserted to my code

php?pll_the_languages()

That ? sign, was causing the error.

Another question that I have is:
Is there a way to show flags as well? When I am calling the function?

Thanks for your time and effort

Edit nevermind found it ??

Thanks @christos !
