update wipes out Posts

  • I just tried to do an auto-update of my WP installation. The system reported the update went OK.

    So I then did an auto-update of two very comoon plugins. That too seemd to go OK.

    But at the end, I got the following error mesages

    QUOTE
    Warning: Unknown: open(/tmp/sess_1aef7a0f3c1d20efef4fbc2b534a0bc9, O_RDWR) failed: Permission denied (13) 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

    ENDQUOTE

    and every Post was gone from my site.

    Fortunately, I had made a full backup before startng. So I was able to restore.

    But my WP is still out o date. I can’t address that until I fix whatever is generating the error msgs and wiping out the Posts.

    Anyone have a suggestion?

  • There seems to of been a permission error on your server within the /tmp directory.

    This will of caused a fatal error and when the update was in progress some files will of failed to update causing issues further down the line.

    Because of this the database won’t of been changed correctly and in result your posts dropped.

    I’d update WordPress manually for now to get your site up to date and then look into the issue with your server administrator around permissions on files and folders for your own needs.

    /tmp is usually fully writable to the world though.
