Returns blank page calling content type or node

Configuration finally complete and error free. Now returns blank page when a content type set with "always" or "per node" is called. Must uncheck phpfreechat on content type or specific node to get the site back. Memory not the issue as it has been increased and increased with other modules before. Any ideas why blank page calling phpfreechat enabled content type or node? Not bothering to upgrade until problem is identified as fixed in newer versions.
