Can't edit page in exihibit after upgrading from 1.5.3 to 2.3

When creating or editing exhibit pages, we can't add content blocks to them. If we go to Exhibits > EXHIBIT NAME > Edit > PAGE NAME, under New Block, we should be able to select a layout and choose Add new content block. When we do this, nothing appears to happen. We have "SetEnv APPLICATION_ENV development" in .htaccess and "debug.exceptions = true" in config.ini. The only error that we can see is in /var/log/httpd/error.log which reads:

[Wed Aug 05 11:28:05 2015] [error] [client] PHP Strict Standards: Declaration of ExhibitBuilder_ExhibitsController::_getBrowseRecordsPerPage() should be compatible with that of Omeka_Controller_AbstractActionController::_getBrowseRecordsPerPage() in /usr/local/data/htdocs/omeka/plugins/ExhibitBuilder/controllers/ExhibitsController.php on line 434, referer:

Sugestions on getting around this so we can edit our exhibits?

Something odd is definitely happening. The message is referring to a function that isn't in the current Exhibit Builder, which should have been what came packaged with Omeka 2.3.

The first thing I'd try is updating the Exhibit Builder plugin to the most current version and see if that resolves it.

Upgrading the plugin seem to have resolved the issue
