[MRBS-general] php fatal error: call to undefined method Calendar::getDaysInMonth() in mincals.inc on line 141

[Andy M. <moo...@gm...>]

An odd error has just popped up on our installation. Any help would be
greatly appreciated.

Our install now just shows the header and then a blank/incomplete page
without the rooms and times.

Server error_log has this:

php fatal error: call to undefined method Calendar::getDaysInMonth() in
mincals.inc on line 141, referrer: day.php

Using latest mrbs 1.4.7

centos 5
apache 2.x
mysql 5.5.18
php 5.3.8

What's odd is that the install appeared to be working fine for a couple
weeks before this error popped up. The only change I made to the server was
to upgrade mysql from 5.5.17 to 5.5.18

Any ideas?

Thanks in advance.
