URL Not Found pnp4nagios

[aelmoqdadi (EL MOQDADI)]

Hi,
When I try to access to any graph in check_mk i get the following error :

Not Found

The requested URL /pro/pnp4nagios/index.php/graph was not found on this server.

Although the pnp4 link works with the link :
/prod/pnp4nagios/index.php/graph

This error appears after my version upgrade and the server change.

I have the same error except when I click on the graph I get:
Function get_magic_quotes_runtime() is deprecated
