Don't get mad It is not worth it

ok, when i wait for reply, i try again all of ways to install and instal from temp from folder is succesfull !
great. But i have problem with Captcha...i retype captcha from image and i always see Anti-spam code is not correct. Please input the code that you can read in the image.
try at www.opatrovatelky.com/opatcom
i think ***_comment_captcha isnt well installed or what

Go to the extensions-> compojoom comment -> settings -> com_content -> open it and close it. This should solve the recaptcha problem.
