[BlueOnyx:24371] New 5209R load - roundcube errors

[Larry Smith]

Just loaded a new 5209R server for a client 
with AV-SPAM, PHP, Roundcube, Wordpress, mysql/mariadb
packages from the BlueOnyx store,
and now getting:

<quote /var/log/httpd/error_log>
PHP Warning:  Declaration of rcmail::get_instance($env = '') should be 
compatible with rcube::get_instance($mode = 0, $env = '') 
in /home/.sites/148/site6/web/roundcube/program/include/rcmail.php on line 30
</quote>

when anyone tries to login to roundcube and the browser returns:
Login failed, or your session id has expired or is invalid.

Any hints or ideas ???
