Hi Paul,
Unfortunately, I cannot. Such messages are coming if something
unexpected happened that needs further investigation for which the
best starting point is the server log. Without that it's hard to say
anything. Sorry about that.
Which version of the portal do you use? Upgrading to a newer version
may also help as the bug that causes the problem may have been fixed
there. But still, the problem would be better to be investigated properly.
Regards,
