Today, I wrote a plugin, facebook like with XFBML. Facebook like share is not showing. I didn't know, why ? I check my code and check my blog. Disable some script and testing. I found it. When I use Facebook share, facebook like can't work and it's conflit javascript vairable. iFrame is no problem. Problem with XFBML. So, if we want to use two things, fblike and fbshare, we must use iframe for fblike. In my plugins, remove application ID and it will work with iframe. So, I decided to change again with iframe in all of my blog. I wanna facebook share and facebook like,too. Share from facebook like is not important for me.
