Question CAPTCHA display problems

Thank you, I did that but it's not resolve the issue.
I also check in both firefox and chrome for mac

You did not make those changes to the file. Look at the file ../templates/rt_tachyon_j16/css/joomla.css at around line 147: Remove or comment out this code like I showed you earlier.

No Man, I did it..
Here's the file

I change extension to txt

Sorry, I see what's happened. You need to force a refresh of your browser cache to see the change. Press CTRL+SHIFT+R and you will see that everything is now working the way that it should be.

Hi, it's still there

And another thing :
Why with secure capthca I still get spammers posting in my forum? (I already delete the posts)
can we add another security like math question maybe? Like I see alot in VB/phpBB forum

Hello all,

I'm running Joomla 2.5, with a Rockettheme template, Carmen, and I've installed the latest version of Kunena, 1.7.2.

I've enabled reCaptcha for my forum post, only for the first 5 post, however I noticed that the reCaptcha function is at the top of my page, partly hiding behind my logo. Which make its impossible for the end users to use it. You can view this at foxapts.com

Now I'm very new to Joomla but I assume its some type of CSS setting I can edit or add, however I have no clue where to start with that and was hoping this has been addressed somewhere and someone could point me in the right direction.

Thanks,
Bob

See the advice given in msg #10; the answer is similar in your case; the actual file name and line numbers will be slightly different.
