Warining

I am sorry if I am bothering you but I can not get this module to work right. I was able to change to php5 and now I am getting this error. I was thinking that I may need to change the permissions of some of my files. I was not sure witch ones to change or if I was even making the right assumptions. I am also on a shared server and .htaccess files do not work. I have to use a php.ini file. Is there anything you can do to help me. Thanks.
