When I was opened my index.php I saw a warning as following:
Warning: open(/tmp\sess_d8371d1d2885a00f831dca4730aa2354, O_RDWR) failed: m (2) in c:/program files/abria merlin/apache/htdocs/md/misc/misc3.php on line 12
I use sessions. Related file (misc3.php) and screen view are added to this e-mail.
You're running Windows, presumably, which does not have a /tmp directory. Open your php.ini file, change the sessions save path value to a real directory on your computer, and then restart your Web server.
