I'm using trial version of NuSphere PHPEdit. I've setup the FTP account but the "Upload File(s)" option appears dimmed/inactive. Do I need to change some settings somewhere?

PhpED allows to have multiple projects in the Workspace. Each with its own account for upload. So you need to specify which one account should be used with a particular project. Open project properties and select account in the dropdown list.

Thank you Dmitri . Problem solved.
