Image broken in Apache and Mysql Apps

Hi,

I have just installed Observium and added apache2 and mysql graphs in Device->Apps

Observium seems to be working fine , but the images related Mysql and Apache graph are broken.

I have followed the apache/mysql instruction step by step , added right permission to the folder, restarted apache but nothing do .. i am still getting the broken link.

Here is the output while enabling the debug variable to 1 in the url - I can confirm that the graph exists in the /tmp dir but nothing showed :
