[Koha] opacmainuserblock

[Victor Barroso Oliveira]

I noticed that, due to the updates, opacmainuserblock was removed from the
Administration interface and directed to the tools -> custom html interface.
However, now I am not able to edit the contents described before the system
update in OPAC. Nor can you find where this information is in the admin
interface to edit or delete it.
Does anyone have a solution for this?
