Apache 2 redirect domain to ip

I've a domain name at OVH ant i've correctly confiigured my DNS to put the DNS to my VPS (where i've installed prestashop), but when i enter my domain name in a web browser it redirect ir correctly to my prestashop but remove the domain name and put the ip adress of my VPS, i've created an conf file for my domain in apache 2 site-available, i've enabled it an reload apache, but the error still persist.

If anyone have a solution, it will be nice to share it with me ^^
