Doesn't work for Joomla 3.3.3

Hello!
Thank you for such a simble but usefull plugin!
Unfortunately it doesn't work for my Joomla 3.3.3.
The code {f90filter...} is processed but rules do not affect the behaviour of the content.
Did you check the compatibility to the newest versions of Joomla (though 3.3.3 is a bit outdated)?

Hello Oleg,

Thanks for showing interest in this plugin.
Please make sure the plugin is enabled. If it is enabled then let me know for which extension you are using Content Filter plugin.

Of course, the plugin is enabled.
I'm using only com_content, i.e. usual article.

Hello,

Please share the screenshot of Plugin configuration, article content and actual display of content?

Hello!
The result below is the same regardless of my status (registered or not logged in).

Hello ,

Are you sure that usergorup of logged in user is Registered? If user is Super user then you need to select that usergroup also.

Oh, I'm confused
It really works
Beg me pardon and thank you very much!
Could you answer one more question? Explain me the difference between Public and Guest, please?

If any user is not logged in then he will have usergroup, Public and Guest.
As user gets logged in, he will have his own usergroups and Public usergroup. So it means Public usergroup is assined to each user and guest usergroup is assigned to non-logged in users.

Hope it make clear.
It will be great if you can share your view on JED extensions.joomla.org/extensions/access-...nt-restriction/25829
