OCSReports is not working

Hello everyone,

I'm actually in a internship and my job is to manage the IT infrastructure with OCS Inventory. So i'm actually using a virutal machine with CentOs 7, i installed OCSNS_LINUX_SERVER and when go to my server's instance with http://serverip/ocsreports this happens :

I think it's a PHP problem but i looked into the php.ini file but it's like chinese for me...

Can someone help me figure out what's happening and how can I fix it ?

Thx for reading,

Best regards
