Fixed in the latest release.
https://github.com/funkjedi/acf-qtranslate/issues/32

Starting with the 1.7.7 release the standard ACF text fields are no longer automatically multilingual. If you want this behaviour you need to enable on the settings page.

You need to use fields from the qTranslate Field Types when setting up your custom fields in ACF.

This should now be working correctly with the latest release.

Fixed in latest release.

Media Library bug with the grid view is now fixed in the latest release.

Closing.

This should do what you’re looking for.

function qtrans_get_field($name, $lang = null) {
	global $q_config;

	// no language specified return in the
	// current language
	if ($lang === null) {
		return get_field($name);
	}

	// switch to given language
	$orig = $q_config['language'];
	$q_config['language'] = $lang;

	// retrive field value
	$value = get_field($name);

	// switch back to the original language
	$q_config['language'] = $orig;

	return $value;
}

If your ACF fields are using the qTranslate field types then you can add this to your functions.php and the switch controls will show up above the fields as well.

add_action('admin_footer', 'qtranslatex_add_switcher_controls');
function qtranslatex_add_switcher_controls() {
?>
<style>
.multi-language-field {margin-top:-38px!important;}
.multi-language-field .wp-switch-editor[data-language] {display:block!important;}
</style>
<?php
}

What screen are you on in the WordPress backend when you get the error?

Try update to the latest version. Based on the code you’ve posted it looks like you’re still using version 1.4.

What version of ACF are you using and what variant of qTranslate are you using (i.e. qTranslate-X, qTranslate Plus, etc)?

This should be resolved in the latest version. Please update and let me know if you’re still experiencing any issues.

No problem. Let me know if you come across any other issues with ACF qTranslate and qTranslate Plus.

Proper support for both the Image and File fields in ACF5PRO was added in a recent release.
