Salut!

1. Action Buttons.
   The only button which is workin' for now is HangUp. All the others have no reaction on clickin', dunno why, rly.. The permissions are ok (:all), user login is correct (the same as in sip.conf u know). So it is impossible to use any operator funcs if u know what I mean..

You must have originate or all permissions in /etc/asterisk/manager.conf read/write lines. Are you sure you have that?

/etc/asterisk/manager.conf
[mark]
secret = mysecret
deny=0.0.0.0/0.0.0.0
permit=127.0.0.1/255.255.255.0
read = system,call,log,verbose,command,agent,user,originate,all
write = system,call,log,verbose,command,agent,user,originate,all

Another possible problem is that you have defined an incorrect FOP2 Custom Permission, for example, if you create a permission named "all", it will break the real "all" permissions from FOP2.

If you want to troubleshot , you can run fop2_server in debug mode, capturing output, and then inspecting that log after you try some actions. Here is a post describing how to do that: View Post 1338#p5240

2. Action Submenu.
   When clickin' a presence icon for any button nothing happens. No submenu u know.

I use asterisk 1.8 (without any freepbx, hate those web GUIs lol xD). My buttons.cfg file looks like this:

[SIP/USER]
type=extension
extension=USER
label=USERname
context=USERcontext
...
and so on.

All the users have :all permissions, so the problem is not about it.

The action submenu appears if you have actions available from that menu. For email, you must set an email address in the fop2 buttons page in FreePBX for every extension. For chat you must have the "chat" permission for your fop2 user as well as a license that includes chat support. For add/remove/pause/unpause, you must see queue buttons on the display.

Best regards,
