I started getting the "Warning: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (C:/PHPSessions) in Unknown on line 0" just a few minutes ago. Sessions were working fine about 10 minutes ago, and I did not touch apache or the php.ini file, yet sessions are no longer working. I am using the latest stable version of PHP. Any clues as to what could be wrong here?
