This plugin exists for over three years and nobody asked for this feature ever before, so IMHO this is not a feature that is worth the effort to implement.

Facebook doesn’t support this. Facebook only supports plain texts, so the plugin strips all markup.

You can try the development version, with the new like button option, if you like:

I am sorry, but there is only support for pro version users. If you are a pro version user, please reply to the pro version activation instructions to get support. There is an extensive FAQ, which might help you solve your problem or answer your question.

Try enabling ‘Share with all users’ in the Easy setup section.

Please reply to the pro activation instructions for personal support.

This plugin is supported, which means that bugs will be fixed. So there is basic level support. Could you please revise your rating to reflect this? Also because ratings are about the plugin and not directly about the support provided. With more than 1,5 million downloads I am pretty sure the plugin works. Look at the version number and you will get an idea about how much effort I have put into this plugin. There is also an extensive FAQ, which give solutions for almost any possible problem.

Please read this too:

Long story short: it is impossible to provide personal support for each and every problem for free and I can really say this, because I have tried it for several years.

Hint: create more than one Facebook application.
