I have been searching the net for the solution to my problem "This modification is not allowed because selection is locked", but I can't find any help that works for me.



I have about 30 different documents, where I have made a lot of cells, locked the document, and opened the cells that the users are allowed to write in and delete in. But today, I can write in the cells, but I can't delete what I just have wrote in the cells - and that is the same for every single document I have. I can open a new blank document, and write and delete in it - but not in my other 30 documents.

If I unlock the documents, I can write and delete as normal, but then the users can change the size of the cells, delete them and all the stuffs that I'm trying to prevent them from doing.

I can see on the net, that those who have the same problem, is because it is a trail version, and that the can't create new documents. But that's not my problem. Everything works just fine, when I unlock my documents, or when I create a new documents.
