I have tried to delete this phrase and change it to just: "Please contact the forum administrator." The phrase is very hurtful and lately my forum has banned two people accidentally. I know for sure that these bannings happened spontaneously.
It seems that now we are not able to change the phrase. We can only change the "translation" of the phrase. Please help me to delete that phrase completely and take control of the phrase that users receive. Thanks!
You should have edited and changed it in Dashboard > Forums > Phrases admin page. Search for that phrase, if you cannot find it, click the [add new] button and add the phrase key identical phrase, and insert the changed version as a phrase value.
