All stores and categories are gone
It seems that there is a problem to retrieve stores and categories from the database. Everything is gone but it till shows that I have 149 stores.
I also get this line at the bottom of the Store page of the admin area:
Warning: Unknown: write failed: No space left on device (28) in Unknown on line 0
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
Does anyone recognize this. I haven't made any changes recently but still this happened. Could this be related to my Cache plugin or CDN?
