I activated document-protection for a document (Open Office on a Macbook, very recent download), and now I can't deactivate it. Though I should be the user who is allowed to read and write, I can't write on it anymore or rename the file. When looking back on the document information it displays no protection, which I could deactivate. Hum?
It's the first time I use Open Office: Actually I just wanted a password-protection for the file.
How hard can it be?
From the menu, select Format -> Sections
Select your section in the left pane and uncheck Write Protected
Enter the password you used when prompted
Click the Remove button on the right side to get rid of the section
Click OK
The other answers are quite old and did not work for me. Therefore, I looked for a newer answer, and found one here.
The solution is to go to
Tools > Options... > LibreOffice Writer > Compatibility,
and then to remove the tick mark from the " Protect form" line. For me, this is the third line from below.
In LibreOffice 7.1.0.3 on a BigSur-M1-MacBook you have to remove the tick of "Enable Cursor" under "Protected Areas" (upper right corner) in Perferences / LibreOffice Writer / Formating Aids.
As you can see from the screenshot I added, there is no option "ignore protection", but to remove the tick from "Enable Cursor" works.
