Hi!

I tried to install the Ccomment on one of my websites. But after pressing Download&Install in my backend office, i recieve this error:

Fatal error: Call to undefined method JDatabaseMySQL::qn() in /home/*****/www/http://fx-abc.ru/tmp/install_52e11b0f948e0/script.php on line 364

Previosly, I instlled this component on another website, on the same hosting, and i have not recieved this error message. The only difference is that, the other webste was ona joomla 3.0 engine. this one is on joomla 2.5.
