H5pMod on live server

Hi,

I worked on a H5Pmod theme on a local moodle and it worked very well. I'm now trying to put it on a test server similar to the one used in production. After adding the theme I went in the theme selector but I get the following error: Fatal error: Cannot redeclare class theme_h5pmod_mod_hvp_renderer in /var/www/timeline/theme/h5pmod/renderers.php on line 0

I didn't change much in the renderers and it was fine on the local moodle. I put the code in copy

<?php

// Be sure to include the H5P renderer so it can be extended
require_once($CFG->dirroot . '/mod/hvp/renderer.php');
