I want to open password protected [not read only] doc file [saved in LibreOffice] to write, but i cant type. How to solve this problem ?
You can toggle the edit mode using this button:
If the file is write-protected, a message will appear. The content of the message depends on the reason for the write protection:
Please keep in mind that there may be two (different) passwords set for a certain document. LibreOffice allows for setting separate passwords to open a file and to edit it:
So, even if it's possible to open a password-protected libreoffice doc, there may be another password set to prevent editing.
If you are the creator of the original file, you can save a copy of the file, edit that, and then overwrite the original later, adding the password when you save.
This is only of course if tohuwawohu's answer does not work for you.
