Netbeans 7.0.1 with PHP 5 and SVN doesn't allow me to save

I'm using netbeans 7.0.1 with SVN PHP 5 project. My problem is that I've made changes in the file and when I try to save it (hitting CTRL+S) I hear the sound like "dimp" and it doesn't save开发者_如何学编程 the file. If I go to File->Save it is disabled.

I already know that if the file is already saved the Save option because disabled, but in this case my change is not saved yet as I close the file, open it again and the change is not there.

Any ideas how to solve it? Thanks in advance! Guillermo.

Maybe you don't have the right permissions on the SVN repository, in that case you should do a "CHECKOUT" of the project to a local folder and edit the files from there. Later on with the right credentials you can "COMMIT" your changes to the repository.
