Thank you for the upload @by_ix - I still thought can't make the sticky note to appear. I searched the support thread on official, and somewhere Jackal, the original creator, said this: https://invisioncommunity.com/forums/topic/438959-sticky-notes-support-topic/page/10/#comment-2727869
I use Taman's theme, specifically Magnum, so it may this the problem, although i can't understand what's custom edit i have to create for it. Anyone with some knowledge and some spare time, tell me to pm him my forum's url ty in advance, i believe Sticky Notes will be a very nice app to have, for guest users, to make them register or for specific members to reply to a thread / follow some procedure.
I looked in my sources, I cleared the manage () function in license.php and cleared the storeNote() function in sources/GlobalNote/GlobalNotes.php.
I also removed the license {} block from the data/acpmenu.json
