i created an essay in a document.
i had edited it, saved it and opened it again without any problems for few
days.
however the last time i tried to open it, it seems to be locked.
i cannot click on any options apart from 'view'
and when i try to edit my essay, 'This modification is not allowed because
the section is locked' appears in the bottom left corner.
how can i change my essay back to normal so i can edit it?

any suggestions will be appreciated, thanks.
