I have a vagrant box with a Magento installation. My var folder is set to 777 (not recommended I know but I'm trying everything). When I try to login to the admin, nothing happens. I see empty session files in the var/session folder.
I have checked the following:
- cookie domain in db (set to empty)
- vagrant box server time equals my local time zone
- use of localhost (I'm not using localhost, i'm using a local.XXXX.com domain)
- cleared all my cookies
- tried various browsers
- tried incognito browser
I keep seeing this in the logs:
Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct [path to correct var/session folder]
but there are empty session files in that folder.
I tried deleting the session folder, and Magento creates it anew but with the empty session files.
I had the same configuration running perfectly, but I had to destroy and rebuild the vagrant box. That is when it started happening.
