Unable to write in the "logs" directory

[kmu...@nmu.edu]

I am upgrading my SPs and IDPs from 1.18.8 to 1.19.1 

With 1.19.1 I receive the following error on the SP that I upgraded 

SimpleSAML\Error\Error: UNHANDLEDEXCEPTION
Backtrace:
1 www/_include.php:17 (SimpleSAML_exception_handler)
0 [builtin] (N/A)
Caused by: RuntimeException: Unable to write in the "logs" directory (/var/simplesaml/simplesamlphp-1.19.1//log/).

My config.php contains 

    'loggingdir' => 'log/',

    'logging.handler' => 'syslog',

I've been running with this setup for years and the logs are definetly being handled by the syslog daemon.  

I tried setting the loggindir to an empty string, but I still get an error.  

I can make the log folder writable, but nothing gets written there. 

I'm guessing there is now a check for write access which wasn't there before?
