    Hi folks,

    Suddenly being greeted with 'A server error occurred. Please try again later'. I cannot login.


    If I navigate to the Admin CP login page, it states:

    Can anybody shed any light? Many thanks!

    Errors of this nature don't occur spontaneously - have any changes been made prior to it starting?

    If not, you may want to contact your host to determine what has caused it.

    You may need to restore from a recent backup (which will result in a loss of any content created since the backup was taken).

    We uploaded around 15 smileys perhaps 10 minutes before the crash - any chance of that being linked?

    No other changes.

    I can't imagine that would be the cause.

    Can you run this query in phpMyAdmin and paste the full text output?
    show create table xf_user;

    We've just restored a MySQL backup from 16 hours ago- I imagine that would render the above querys output useless?

    Slightly concerned this is from an outside influence. Gone ahead and changed pw's and disabled SHELL.
