Here's the story.
It involves a human and system confusion about the distinction between a "scheduled conference" and the parent "conference".
We were attempting to add this content at the parent "conference" level.
The PHP error we tracked down follows:
PHP Fatal error: Call to a member function getLocalizedSetting() on a non-object in /var/www/html/ocs/cache/t_compile/%%7E^7E1^7E1EBAAB%%editorialPolicies.tpl.php on line 13, referer: http://ocsdev.lib.uoguelph.ca/index.php ... ndex/about
It was looking for a variable value for the "scheduled conference" but since we were at the parent level that value was missing.
We now seem to be bypassing the parent conference and the "about" content works perfectly at the "scheduled conference" level.
I hope this makes sense.
