How did you remove buttons? It is not possible to remove buttons via the FOP2 Manager, that is why I am asking. In any case, whatever you see or not is a result of the configuration. When using the FOP2 Manager, you must have in fop2.cfg the line
#exec autoconfig-users.sh
And nothing else, no user=xx line, no buttonfile=xx line (for manual configurations), as config will overlap and it won't work as you might expect.
In order to "see" the configuration that comes from the FOP2 Manager, you can run in the command line those scripts:
/usr/local/fop2/autoconfig-buttons.sh
And inspect the output. If you see valid configuration for buttons, then you are in the right direction. If you see blank or errors, those will give you a clue of what the problem might be.
Finally, a common error for new users is try to create permission or groups in the FOP2 Manager without actually knowing what are there for. My advise in that case is to NOT create any groups or permissions. Edit your User and uncheck any groups it might have assigned. Set permissions in the User tab to "all". Restart FOP2 and try from there. That is the most "open" config possible, with no restrictions. *anything* you can do from the Manager after that is for RESTRICTING views or permissions, that means, REMOVING buttons from view, or REMOVING the possibility to perform actions.
So, for starters, leave it all open/unrestricted. See if it works or work your way until it works. Then think about changing permissions, or limiting views with groups.
