hide comment in front page not working

There's 2 possibilities here.
1) Frontpage is somewhat of a bad name. When we say "Frontpage" we're talking about menu items that are showing "Articles -> Front Page", not necessarily just your home page. Can you tell us what type of menu item you're seeing the Likes & Comments on? That will help us narrow it down further. I never liked Joomla's naming for "Frontpage", and fortunately, that's been changed in Joomla 1.6.
2) Obviously, we could have a bug. We've tested those options pretty extensively though, and we haven't heard of this problem yet, so it's probably a misunderstanding somehow. We'll do some more testing to see if we can recreate this in some case.

Let us know if this helps or not!

In this case, the setting you'd want to disable in the "xxx in Article" option, because you're displaying an article. This will disable it for all individual article views though. The other option would be to use CSS to specifically hide the Like and/or Comment box on the home page.

Unfortunately, the "Show in Front Page" setting does not mean "Home Page", that's just the terminology that Joomla uses for the Frontpage blog view.

Hope this helps, and if you have any questions on how to do the above, just let us know.

The JFBCContent plugin will insert the Comments and Like widgets surrounded by divs with id's of jfbccomments or jfbclike. On the menu item for the home page article, in the "System Parameters", you can specify a Page Class Suffix. For example, try using "-homepage". This will add a div like around your article. With these two classes, you can add something like the following to your CSS file to hide either of the Like or Comment boxes:

No problem. I hope that works for you. Please let us know!
