Undefined "rcmail::request_security_check"

[nedludd]

Roundcube (tested with 1.1.4 and 1.2-beta) does not seem to be able to find this function. 

I get this in the logs and the screen is blank:

Code Select Expand


[14-Jan-2016 19:38:09 GMT] PHP Fatal error:  Call to undefined method rcmail::request_security_check() in /usr/share/apache2/roundcubemail-1.2-beta/index.php on line 177

Any idea why, and what I can do to fix it, short of commenting it out?

I mean there's no doubt "program/include/rcmail.php", where that function is defined, is  getting sourced...

Thanks
