I cant paste anything i copy

No matter what i copy, libreoffice refuses to paste it.

Sometimes (very rarely) this happen to me as well, but if you are using shortcuts (CTRL + C and CTRL + V), try to use menu instead (Edit → copy and Edit → Paste)… I have no idea why is this happening.

First try to paste to some other program, to see if paste is working there. If yes, then try to restart LibreOffice.

Please tell us: (1) what operating system you are using (Win? Linux? or?); and (2) what your keyboard localization is. As Ljiljan noted, shortcut key operations can be affected by the keyboard that you have activated.

I had the same problem, turns out I had more than one sheet selected: To “fix” this right click on any of the sheets and click the “Deselect all Sheets” option.

it is work. I first sellect all sheet then desellect it.
Thank you so much
