Today strangely i saw an error in my wp-admin dashboard, the error is this
Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0
I quickly did a search on wordpress forums and on Google but couldn’t find an answer for this. After a close look at the error i figured out it is because tmp folder is not there on my account. Previously this blog is on my own server and i didn’t have this problem, but last week i moved this one to dreamhost temporarily because of heavy load on my server. Dreamhost accounts don’t come with tmp folder that is why this problem.
This worked for me, if you know any other reason for this comment here.
