[Plugin: WP Survey And Quiz Tool] Language Swap – qTranslate

I’ve solved it!!!
inside the directory:
pages/site/quiz

edit section.php
… <form method=”post” action=”<?php echo esc_url($_SERVER[‘REQUEST_URI’]); ?>”>

like that:

<?php if(qtrans_getLanguage() == “it”) : ?>
<form method=”post” action=”<?php echo esc_url($_SERVER[‘REQUEST_URI’]); ?>?lang=it”>
<?php endif ?>
<?php if(qtrans_getLanguage() == “en”) : ?>
<form method=”post” action=”<?php echo esc_url($_SERVER[‘REQUEST_URI’]); ?>?lang=en”>
<?php endif ?>
<?php if(qtrans_getLanguage() == “ru”) : ?>
<form method=”post” action=”<?php echo esc_url($_SERVER[‘REQUEST_URI’]); ?>?lang=ru”>
<?php endif ?>

Hi all,

I would like to swap language in WP Survey and Quiz Tool (version 2.13.1).
In the folder ‘wp-content/plugins/wp-survey-and-quiz-tool/lang’, there are many languages files (.mo extension):
– wp-survey-and-quiz-tool-es_ES.mo
– wp-survey-and-quiz-tool-it_IT.mo
– …

In this folder, there is an other folder named ‘po’ with another languages files (.po extension):
– es_ES.po
– it_IT.po
– …

Please, how I can change the language on this plugin? I don’t find where I can precise which language (so which files) I want to use.

Thanks for your support !
