[SR-Users] Error using newest Siremis and kamailio 5.0.3

[Olli Attila]

Hello,

I installed Siremis today from master branch alongside with Kamailio 
5.0.3 and entering "XMLRPC Commands" menu gives me this error:

[2018-03-01 12:28:34 (GMT)] An exception occurred while executing this 
script:
Error message: #256, Unable to location template file 
system_internal_error.tpl.
Script name and line number of error: 
/var/www/html/https/siremis/openbiz/bin/Resource.php:283

(I'm running PHP 7.0.27-0+deb9u1 and MariaDb Server version: 5.1.73 
Source distribution)

What is going wrong here?

I found this online but I think this is already fixed on the Siremis 
master branch?
