been running fine for a few months has suddenly started generating the
following error - a re-start of sever has not fixed the problem, nothing
similar on mailing list - last known change was adding 2 administrative
users and disabling one a few hours prior to going offline, any and all
assistance/advice is very much appreciated.<br><br>
com.opencms.core.CmsException: 0 Unknown exception. Detailed error:
CmsException ID: 0. <br>
