Recently my ISP added imap functionality to my webserver. After the installation they recompiled PHP. But the hostingclients on my server are including from a specific hostingaccount on the server. By adding an extra include_path to the CMS folder the websites are able to communicate with the CMS and database. The strange thing is that after recompiling PHP the 'client-accounts' can't include my CMS files anymore. I'm prompted with the traditional error 'failed to open stream'.
I've tried to add the includepath in the php.ini, but as i expected without any result. Do you have any idea why the include_path is getting ignored/excluded/overruled? Are there perhaps other settings in php.ini which need to be set?
P.s. my server is configured without suPHP (I've been told by my ISP).
It's solved by the ISP now. Open basedir restrections were the problem. I turned them off and now it works again :)
