I have a document library with some excel files, and a content query web part that displays these files.
From within the document library i can open all the documents in read/edit mode without any problem. In content query web part, all the files work fine, but for one single file it opens the file only in ready only mode, and i cant edit it anyhow. When i make some changes and try to save it says that i need to save it in other location and then upload. I couldnt find anything specific to this file, but just for that one single file from within the content query web part it opens only in read only mode, same file is absolutely fine in when i open it from document library.
