That looks like your censorship kicking in.
In admin go to:
Preferences Main »» Word Censoring Options
In your word sensor list make sure you do not end with a | which I once found out, lol.
for example:
1word|2word|3word
not like this:
1word|2word|3word|
You can also edit your bad word censor from #oops# to something else.
Or if you don't require word censorship then just turn it off.
Hope this is of help.
