Unable to save Growth Journal entries.

Hello.  I haven't been able to save any Growth Journal entries in the last several days.  I keep receiving errors which also indicate the developers have been notified.  This has been happening on Safari v.6.0.2, the latest version.  I also recently upgraded to Mac OS 8 - Mountain Lion, so I don't know if this problem is relative to that fact.  I tested this in Firefox 17.0.1 (latest for Mac OS).  It allowed me to save one entry I only populated with the world "test."  I went to edit that and content which then duplicated the error in Safari browser.
