Here it should be :
$boxes[$box_id]['mi']['conn']="/tmp/opensips_fifo";
...but maybe is just a typo.

Looking at that error it seems like for some reason PHP cannot create the fifo reply file.
The ideea is that the command is first written to a fifo file  (/tmp/opensips_fifo) and 
then the answer is read from another file - a reply fifo file.
 From opensips-cp/config/tools/mi/local.php.inc :

$config->reply_fifo_filename="webfifo_".rand();
$config->reply_fifo_path="/tmp/".$config->reply_fifo_filename;

This file gets deleted after each MI command , so dont be surprised if its not there.

But on most linux distros apache has rights to create files into /tmp by default , since 
/tmp is mode 777 . Maybe your /tmp has different mode ?

Thats the first suggestion.

The second suggestion would be to check your php.ini and see if PHP is allowed to call 
system().
OCP is using system() to issue a  "mkfifo -m 666 $config->reply_fifo_path" command.
Maybe Safe_mode is on or other security restrictions are on .
