I was using the 2.40 version of !JoomlaComment, I uninstall it and install the 3.26 version. It is working.
The problem is that all the OLD comments have now strange characters (ÃÃ³€±) My web is in spanish. I try the "Convert to iso-8859-1" function but give me an error: "Local charset is empty ! check your setting"
¿What do I have to do?
