Fatal error Polylang

Hi,

I just downloaded Polylang for my website, but I keep have this fatal error now and can’t access to my dashboard anymore.

Fatal error: Cannot redeclare icl_register_string() (previously declared in /nfs/c09/h04/mnt/129484/domains/hotel-luz.com/html/wp-content/plugins/polylang/modules/wpml/wpml-compat.php:226) in /nfs/c09/h04/mnt/129484/domains/hotel-luz.com/html/wp-content/plugins/wpml-string-translation/inc/functions.php on line 271

What can I do ?
